9114Context2-Aminoadipic 2-Oxoadipic AciduriaIt is a metabolic disorder characterized by increased levels of 2-oxoadipate and 2-hydroxyadipate in the urine. Patients can have mild to severe intellectual disability, muscular hypotonia, developmental delay, ataxia, and epilepsy. Most cases are asymptomatic. DiseasePW121907CenterPathwayVisualizationContext12218336003000#000099PathwayVisualization6435964475Lysine DegradationThe degradation of L-lysine happens in liver and it is consisted of seven reactions. L-Lysine is imported into liver through low affinity cationic amino acid transporter 2 (cationic amino acid transporter 2/SLC7A2). Afterwards, L-lysine is imported into mitochondria via mitochondrial ornithine transporter 2. L-Lysine can also be obtained from biotin metabolism. L-Lysine and oxoglutaric acid will be combined to form saccharopine by facilitation of mitochondrial alpha-aminoadipic semialdehyde synthase, and then, mitochondrial alpha-aminoadipic semialdehyde synthase will further breaks saccharopine down to allysine and glutamic acid. Allysine will be degraded to form aminoadipic acid through alpha-aminoadipic semialdehyde dehydrogenase. Oxoadipic acid is formed from catalyzation of mitochondrial kynurenine/alpha-aminoadipate aminotransferase on aminoadipic acid. Oxoadipic acid will be further catalyzed to form glutaryl-CoA, and glutaryl-CoA converts to crotonoyl-CoA, and crotonoyl-CoA transformed to 3-hydroxybutyryl-CoA. 3-Hydroxybutyryl-CoA will form Acetyl-CoA as the final product through the intermediate compound: acetoacetyl-CoA. Acetyl-CoA will undergo citric acid cycle metabolism. Carnitine is another key byproduct of lysine metabolism (not shown in this pathway).

is an essential amino acid. Normal requirements for lysine have been found to be about 8 g per day or 12 mg/kg in adults. Children and infants need more- 44 mg/kg per day for an eleven to-twelve-year old, and 97 mg/kg per day for three-to six-month old. Lysine is highly concentrated in muscle compared to most other amino acids. Lysine is high in foods such as wheat germ, cottage cheese and chicken. Of meat products, wild game and pork have the highest concentration of lysine. Fruits and vegetables contain little lysine, except avocados. Normal lysine metabolism is dependent upon many nutrients including niacin, vitamin B6, riboflavin, vitamin C, glutamic acid and iron. Excess arginine antagonizes lysine. Several inborn errors of lysine metabolism are known. Most are marked by mental retardation with occasional diverse symptoms such as absence of secondary sex characteristics, undescended testes, abnormal facial structure, anemia, obesity, enlarged liver and spleen, and eye muscle imbalance. Lysine also may be a useful adjunct in the treatment of osteoporosis. Although high protein diets result in loss of large amounts of calcium in urine, so does lysine deficiency. Lysine may be an adjunct therapy because it reduces calcium losses in urine. Lysine deficiency also may result in immunodeficiency. Requirements for this amino acid are probably increased by stress. Lysine toxicity has not occurred with oral doses in humans. Lysine dosages are presently too small and may fail to reach the concentrations necessary to prove potential therapeutic applications. Lysine metabolites, amino caproic acid and carnitine have already shown their therapeutic potential. Thirty grams daily of amino caproic acid has been used as an initial daily dose in treating blood clotting disorders, indicating that the proper doses of lysine, its precursor, have yet to be used in medicine. Low lysine levels have been found in patients with Parkinson's, hypothyroidism, kidney disease, asthma and depression. The exact significance of these levels is unclear, yet lysine therapy can normalize the level and has been associated with improvement of some patients with these conditions. Abnormally elevated hydroxylysines have been found in virtually all chronic degenerative diseases and coumadin therapy. The levels of this stress marker may be improved by high doses of vitamin C. Lysine is particularly useful in therapy for marasmus (wasting) and herpes simplex. It stops the growth of herpes simplex in culture, and has helped to reduce the number and occurrence of cold sores in clinical studies. Dosing has not been adequately studied, but beneficial clinical effects occur in doses ranging from 100 mg to 4 g a day. Higher doses may also be useful, and toxicity has not been reported in doses as high as 8 g per day. Diets high in lysine and low in arginine can be useful in the prevention and treatment of herpes. Some researchers think herpes simplex virus is involved in many other diseases related to cranial nerves such as migraines, Bell's palsy and Meniere's disease. Herpes blister fluid will produce fatal encephalitis in the rabbit.

In the TCA cycle, AKG is decarboxylated to succinyl-CoA and carbon dioxide by AKG dehydrogenase, which functions as a key control point of the TCA cycle. Additionally, AKG can be generated from isocitrate by oxidative decarboxylation catalyzed by the enzyme known as isocitrate dehydrogenase (IDH). In addition to these routes of production, AKG can be produced from glutamate by oxidative deamination via glutamate dehydrogenase, and as a product of pyridoxal phosphate-dependent transamination reactions (mediated by branched-chain amino acid transaminases) in which glutamate is a common amino donor. AKG is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and inhibits protein degradation in muscles. In particular, AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in skeletal muscles (PMID: 26759695). Interestingly, enteric feeding of AKG supplements can significantly increase circulating plasma levels of hormones such as insulin, growth hormone, and insulin-like growth factor-1 (PMID: 26759695). It has recently been shown that AKG can extend the lifespan of adult C. elegans by inhibiting ATP synthase and TOR (PMID: 24828042). In combination with molecular oxygen, alpha-ketoglutarate is required for the hydroxylation of proline to hydroxyproline in the production of type I collagen. A recent study has shown that alpha-ketoglutarate promotes TH1 differentiation along with the depletion of glutamine thereby favouring Treg (regulatory T-cell) differentiation (PMID: 26420908). alpha-Ketoglutarate has been found to be associated with fumarase deficiency, 2-ketoglutarate dehydrogenase complex deficiency, and D-2-hydroxyglutaric aciduria, which are all inborn errors of metabolism (PMID: 8338207).328-50-7C0002651309152-KETOGLUTARATE50DB02926OC(=O)CCC(=O)C(O)=OC5H6O5InChI=1S/C5H6O5/c6-3(5(9)10)1-2-4(7)8/h1-2H2,(H,7,8)(H,9,10)KPGXRSRHYNQIFN-UHFFFAOYSA-N2-oxopentanedioic acid146.0981146.021523302-0.442oxoglutarate0-2FDB0033612-ketoglutarate;2-ketoglutaric acid;2-oxo-1,5-pentanedioate;2-oxo-1,5-pentanedioic acid;2-oxoglutarate;2-oxoglutaric acid;2-oxopentanedioate;2-oxopentanedioic acid;Oxoglutarate;Alpha-ketoglutaric acid;Oxoglutaric acid;A-ketoglutarate;A-ketoglutaric acid;Alpha-ketoglutarate;α-ketoglutarate;α-ketoglutaric acidPW_C000134AKG1524231414146849918673311108421263514475014552614675453751035414117543811855641326008147603615560691576092161648217865308574712227515224751915182092258374220118631981268128977054253771351337748111177523112777461297796734577970346779763277798434778425334800183688069413511316294119972406120022124120084407120174122120552414120814418120989408121146423121152424121160425122757120122831119123186450123399454123554374123718458123724459123732460125357479125400299125455481125533297125800489125929482126900501126940388126993206127066205127255506127388502189SaccharopineHMDB0000279Saccharopine is an intermediate in the degradation of lysine, formed by the condensation of lysine and alpha-ketoglutarate. The saccharopine pathway is the main route for lysine degradation in mammals, and its first two reactions are catalyzed by enzymatic activities known as lysine-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH), which reside on a single bifunctional polypeptide (LOR/SDH) (EC 1.5.1.8). The reactions involved with saccharopine dehydrogenases have very strict substrate specificity for L-lysine, 2-oxoglutarate, and NADPH. LOR/SDH has been detected in a number of mammalian tissues, mainly in the liver and kidney, contributing not only to the general nitrogen balance in the organism but also to the controlled conversion of lysine into ketone bodies. A tetrameric form has also been observed in human liver and placenta. LOR activity has also been detected in brain mitochondria during embryonic development, and this opens up the question of whether or not lysine degradation has any functional significance during brain development. As a result, there is now a new focus on the nutritional requirements for lysine in gestation and infancy. Finally, LOR and/or SDH deficiencies seem to be involved in a human autosomal genetic disorder known as familial hyperlysinemia, which is characterized by serious defects in the functioning of the nervous system and characterized by a deficiency in lysine-ketoglutarate reductase, saccharopine dehydrogenase, and saccharopine oxidoreductase activities. Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation (PMID: 463877, 10567240, 10772957, 4809305). If present in sufficiently high levels, saccharopine can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Saccharopine is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). Many affected children with organic acidemias experience intellectual disability or delayed development.997-68-2C0044916055616927SACCHAROPINE141086DB04207N[C@@H](CCCCN[C@@H](CCC(O)=O)C(O)=O)C(O)=OC11H20N2O6InChI=1S/C11H20N2O6/c12-7(10(16)17)3-1-2-6-13-8(11(18)19)4-5-9(14)15/h7-8,13H,1-6,12H2,(H,14,15)(H,16,17)(H,18,19)/t7-,8-/m0/s1ZDGJAHTZVHVLOT-YUMQZZPRSA-N(2S)-2-{[(5S)-5-amino-5-carboxypentyl]amino}pentanedioic acid276.2863276.132136382-1.725saccharopine0-1FDB000461(s)-n-(5-amino-5-carboxypentyl)-l-glutamic acid;L-n-(5-amino-5-carboxypentyl)-glutamic acid;L-saccharopin;L-saccharopine;N(6)-(l-1,3-dicarboxypropyl)-l-lysine;N-(5-amino-5-carboxypentyl)-l-glutamic acid;N-(5-amino-5-carboxypentyl)-glutamic acid;N-[(5s)-5-amino-5-carboxypentyl]-l-glutamic acid;N6-(l-1,3-dicarboxypropyl)-l-lysine;Saccharopin;Epsilon-n-(l-glutar-2-yl)-l-lysine;N-[(s)-5-amino-5-carboxypentyl]-l-glutamic acid;SaccharopinePW_C000189Sacchar10663822115178276112120781407123373119143NADPHMDB0000217Nicotinamide adenine dinucleotide phosphate.

It appears colorless to the naked eye in small quantities, though it is actually slightly blue in color. It covers 71% of Earth's surface. Current estimates suggest that there are 1.4 billion cubic kilometers (330 million m3) of it available on Earth, and it exists in many forms. It appears mostly in the oceans (saltwater) and polar ice caps, but it is also present as clouds, rain water, rivers, freshwater aquifers, lakes, and sea ice. Water in these bodies perpetually moves through a cycle of evaporation, precipitation, and runoff to the sea. Clean water is essential to human life. In many parts of the world, it is in short supply. From a biological standpoint, water has many distinct properties that are critical for the proliferation of life that set it apart from other substances. It carries out this role by allowing organic compounds to react in ways that ultimately allow replication. All known forms of life depend on water. Water is vital both as a solvent in which many of the body's solutes dissolve and as an essential part of many metabolic processes within the body. Metabolism is the sum total of anabolism and catabolism. In anabolism, water is removed from molecules (through energy requiring enzymatic chemical reactions) in order to grow larger molecules (e.g. starches, triglycerides and proteins for storage of fuels and information). In catabolism, water is used to break bonds in order to generate smaller molecules (e.g. glucose, fatty acids and amino acids to be used for fuels for energy use or other purposes). Water is thus essential and central to these metabolic processes. Water is also central to photosynthesis and respiration. Photosynthetic cells use the sun's energy to split off water's hydrogen from oxygen. Hydrogen is combined with CO2 (absorbed from air or water) to form glucose and release oxygen. All living cells use such fuels and oxidize the hydrogen and carbon to capture the sun's energy and reform water and CO2 in the process (cellular respiration). Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H+, that is, a proton) donor, can be neutralized by a base, a proton acceptor such as hydroxide ion (OH-) to form water. Water is considered to be neutral, with a pH (the negative log of the hydrogen ion concentration) of 7. Acids have pH values less than 7 while bases have values greater than 7. Stomach acid (HCl) is useful to digestion.

It is not among the essential amino acids. Glutamate is a key molecule in cellular metabolism. In humans, dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel or other functional roles in the body. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain. Glutamate transporters are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: * Damage to mitochondria from excessively high intracellular Ca2+. * Glu/Ca2+-mediated promotion of transcription factors for pro-apoptotic genes, or downregulation of transcription factors for anti-apoptotic genes. Excitotoxicity due to glutamate occurs as part of the ischemic cascade and is associated with stroke and diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimer's disease. glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarization around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization.

It is an intermediate in the metabolism (i.e. breakdown or degradation) of lysine and saccharopine. It antagonizes neuroexcitatory activity modulated by the glutamate receptor N-methyl-D-aspartate (NMDA). Aminoadipic acid has also been shown to inhibit the production of kynurenic acid, a broad spectrum excitatory amino acid receptor antagonist, in brain tissue slices (PMID: 8566117). Recent studies have shown that aminoadipic acid is elevated in prostate biopsy tissues from prostate cancer patients (PMID: 23737455). Mutations in DHTKD1 (dehydrogenase E1 and transketolase domain-containing protein 1) have been shown to cause human 2-aminoadipic aciduria and 2-oxoadipic aciduria via impaired decarboxylation of 2-oxoadipate to glutaryl-CoA, which is the last step in the lysine degradation pathway (PMID: 23141293). Aging, diabetes, sepsis, and renal failure are known to catalyze the oxidation of lysyl residues to form 2-aminoadipic acid in human skin collagen and potentially other tissues (PMID: 18448817). Proteolytic breakdown of these tissues can lead to the release of free 2-aminoadipic acid. Studies in rats indicate that aminoadipic acid (along with the three branched-chain amino acids - leucine, valine, and isoleucine) levels are elevated in the pre-diabetic phase and so aminoadipic acid may serve as a predictive biomarker for the development of diabetes (PMID: 15389298). Long-term hyperglycemia of endothelial cells can also lead to elevated levels of aminoadipate which is thought to be a sign of lysine breakdown through oxidative stress and reactive oxygen species (ROS) (PMID: 21961526). 2-Aminoadipate is a potential small-molecule marker of oxidative stress (PMID: 21647514). Therefore, depending on the circumstances aminoadipic acid can act as an acidogen, a diabetogen, an atherogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A diabetogen is a compound that can lead to type 2 diabetes. An atherogen is a compound that leads to atherosclerosis and cardiovascular disease. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of aminoadipic acid are associated with at least two inborn errors of metabolism including, 2-aminoadipic aciduria and 2-oxoadipic aciduria. Aminoadipic acid is an organic acid and abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, kidney abnormalities, liver damage, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. As a diabetogen, serum aminoadipic levels appear to regulate glucose homeostasis and have been highly predictive of individuals who later develop diabetes (PMID: 24091325). In particular, aminoadipic acid lowers fasting plasma glucose levels and enhances insulin secretion from human islets. As an atherogen, aminoadipic acid has been found to be produced at high levels via protein lysine oxidation in atherosclerotic plaques (PMID: 28069522).542-32-5C0095646937024CPD-468456NC(CCCC(O)=O)C(O)=OC6H11NO4InChI=1S/C6H11NO4/c7-4(6(10)11)2-1-3-5(8)9/h4H,1-3,7H2,(H,8,9)(H,10,11)OYIFNHCXNCRBQI-UHFFFAOYSA-N2-aminohexanedioic acid161.1558161.068807845-0.693aminoadipic acid0-1FDB021812(+/-)-2-aminoadipate;(+/-)-2-aminoadipic acid;2-aminoadipate;2-aminoadipic acid;Aminoadipate;Dl-2-aminoadipate;Dl-2-aminoadipic acid;Dl-2-aminohexanedioate;Dl-2-aminohexanedioic acid;Dl-a-aminoadipate;Dl-a-aminoadipic acid;Dl-alpha-aminoadipate;Dl-alpha-aminoadipic acid;L-2-aminoadipate;L-2-aminoadipic acid;L-2-aminohexanedioate;L-2-aminohexanedioic acid;L-alpha-aminoadipate;L-alpha-aminoadipic acid;A-aminoadipate;A-aminoadipic acid;Alpha-amino-adipic acid;Alpha-aminoadipate;Alpha-aminoadipic acid;Aad;Aminoadipic acidPW_C000390AAD10693822715178278112120785407123376119150Oxoadipic acidHMDB00002252-Oxoadipic acid is produced from lysine in the cytosol of cells via the saccharopine and the pipecolic acid pathways. Catabolites of hydroxylysine and tryptophan enter these pathways as 2-aminoadipic-semialdehyde and 2-oxoadipate, respectively. In the mitochondrial matrix, 2-oxoadipate is decarboxylated to glutaryl-CoA by the 2-oxoadipate dehydrogenase complex and then converted into acetyl-CoA. Chronically high levels of oxoadipic acid are associated with at least two inborn errors of metabolism, including 2-aminoadipic aciduria and 2-oxoadipic aciduria. 2-Oxoadipic aciduria is an inborn error of metabolism involving lysine, tryptophan, and hydroxylysine, in which abnormal quantities of 2-aminoadipic acid are found in body fluids along with 2-oxoadipic acid. Patients with 2-oxoadipic acidemias are mentally retarded with hypotonia or seizures. 2-Oxoadipic aciduria can occur in patients with Kearns-Sayre syndrome, a progressive disorder with onset prior to 20 years of age in which multiple organ systems are affected. Affected individuals have progressive external ophthalmoplegia (PEO) and retinopathy, both of which are classically associated with abnormalities in cardiac conduction, cerebellar signs, and elevated cerebrospinal fluid protein (PMID: 10655159, 16183823, 11083877). When present in sufficiently high levels, oxoadipic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Oxoadipic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis.

These are organic compounds containing a (R)-3-hydroxyl acylated coenzyme A derivative. 3-Hydroxybutyryl-CoA is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). 3-Hydroxybutyryl-CoA has been primarily detected in urine. Within the cell, 3-hydroxybutyryl-CoA is primarily located in the mitochondria, peroxisome and cytoplasm. In humans, 3-hydroxybutyryl-CoA is involved in the lysine degradation pathway, the pyridoxine dependency with seizures pathway, the fatty acid metabolism pathway, and the butyrate metabolism pathway. 3-Hydroxybutyryl-CoA is also involved in several metabolic disorders, some of which include medium chain acyl-CoA dehydrogenase deficiency (mcad), the ethylmalonic encephalopathy pathway, the hyperlysinemia II or saccharopinuria pathway, and very-long-chain acyl CoA dehydrogenase deficiency (vlcad). 3-Hydroxybutyryl-CoA is a substrate for Enoyl-CoA hydratase (mitochondrial), Trifunctional enzyme alpha subunit (mitochondrial) and Peroxisomal bifunctional enzyme.2871-66-1C03561440045154522-METHYL-3-HYDROXY-BUTYRYL-COA389056C[C@@H](O)CC(=O)SCCNC(=O)CCNC(=O)C(O)C(C)(C)COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H]([C@H](O)[C@@H]1OP(O)(O)=O)N1C=NC2=C1N=CN=C2NC25H42N7O18P3SInChI=1S/C25H42N7O18P3S/c1-13(33)8-16(35)54-7-6-27-15(34)4-5-28-23(38)20(37)25(2,3)10-47-53(44,45)50-52(42,43)46-9-14-19(49-51(39,40)41)18(36)24(48-14)32-12-31-17-21(26)29-11-30-22(17)32/h11-14,18-20,24,33,36-37H,4-10H2,1-3H3,(H,27,34)(H,28,38)(H,42,43)(H,44,45)(H2,26,29,30)(H2,39,40,41)/t13-,14-,18-,19-,20?,24-/m1/s1QHHKKMYHDBRONY-JYMPOPDUSA-N{[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-4-hydroxy-2-({[hydroxy({hydroxy[(3R)-3-hydroxy-3-({2-[(2-{[(3S)-3-hydroxybutanoyl]sulfanyl}ethyl)carbamoyl]ethyl}carbamoyl)-2,2-dimethylpropoxy]phosphoryl}oxy)phosphoryl]oxy}methyl)oxolan-3-yl]oxy}phosphonic acid853.623853.151987801-2.3210(S)-3-hydroxybutanoyl-coa0-4FDB022460(3r)-3-hydroxybutanoyl-coa;(3r)-3-hydroxybutanoyl-coenzyme a;(r)-3-hydroxybutanoyl-coa;(r)-3-hydroxybutanoyl-coenzyme a;(s)-3-hydroxybutanoyl-coa;(s)-3-hydroxybutanoyl-coenzyme a;3-hydroxybutanoyl-coa;3-hydroxybutanoyl-coenzyme a;3-hydroxybutyryl-coa;3-hydroxybutyryl-coenzyme a;3-oh-butyryl-coa;3-oh-butyryl-coenzyme a;Hydroxy-butyryl-coa;Hydroxy-butyryl-coenzyme a;Beta-hydroxybutyryl-coa;Beta-hydroxybutyryl-coenzyme a;Beta-hydroxybutyryl-s-coa;Beta-hydroxybutyryl-s-coenzyme aPW_C0009043HB-CoA5904108535277103700116182382261523815177257133782801121202824061207904071229471201233801191256214791271485011345Crotonoyl-CoAHMDB0002009Crotonoyl-CoA is an important component in several metabolic pathways, notably fatty acid and amino acid metabolism. It is the substrate of a group of enzymes acyl-Coenzyme A oxidases 1, 2, 3 (E.C.: 1.3.3.6) corresponding to palmitoyl, branched chain, and pristanoyl, respectively, in the peroxisomal fatty acid beta-oxidation, producing hydrogen peroxide. Abnormality of this group of enzymes is linked to coma, dehydration, diabetes, fatty liver, hyperinsulinemia, hyperlipidemia, and leukodystrophy. It is also a substrate of a group of enzymes called acyl-Coenzyme A dehydrogenase (E.C.:1.3.99-, including 1.3.99.2, 1.3.99.3) in the metabolism of fatty acids or branched chain amino acids in the mitochondria (Rozen et al., 1994). Acyl-Coenzyme A dehydrogenase (1.3.99.3) has shown to contribute to kidney-associated diseases, such as adrenogential syndrome, kidney failure, kidney tubular necrosis, homocystinuria, as well as other diseases including cretinism, encephalopathy, hypoglycemia, medium chain acyl-CoA dehydrogenase deficiency. The gene (ACADS) also plays a role in theta oscillation during sleep. In addition, crotonoyl-CoA is the substrate of enoyl coenzyme A hydratase (E.C.4.2.1.17) in the mitochondria during lysine degradation and tryptophan metabolism, benzoate degradation via CoA ligation; in contrast it is the product of this enzyme in the butanoate metabolism. Moreover, it is produced from multiple enzymes in the butanoate metabolism pathway, including 3-Hydroxybutyryl-CoA dehydratase (E.C.:4.2.1.55), glutaconyl-CoA decarboxylase (E.C.: 4.1.1.70), vinylacetyl-CoA Δ-isomerase (E.C.: 5.3.3.3), and trans-2-enoyl-CoA reductase (NAD+) (E.C.: 1.3.1.44). In lysine degradation and tryptophan metabolism, crotonoyl CoA is produced by glutaryl-Coenzyme A dehydrogenase (E.C.:1.3.99.7) lysine and tryptophan metabolic pathway. This enzyme is linked to type-1glutaric aciduria, metabolic diseases, movement disorders, myelinopathy, and nervous system diseases.102680-35-3C00877528038115473CPD-10834444072C\C=C\C(=O)SCCNC(=O)CCNC(=O)C(O)C(C)(C)COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H]([C@H](O)[C@@H]1OP(O)(O)=O)N1C=NC2=C(N)N=CN=C12C25H40N7O17P3SInChI=1S/C25H40N7O17P3S/c1-4-5-16(34)53-9-8-27-15(33)6-7-28-23(37)20(36)25(2,3)11-46-52(43,44)49-51(41,42)45-10-14-19(48-50(38,39)40)18(35)24(47-14)32-13-31-17-21(26)29-12-30-22(17)32/h4-5,12-14,18-20,24,35-36H,6-11H2,1-3H3,(H,27,33)(H,28,37)(H,41,42)(H,43,44)(H2,26,29,30)(H2,38,39,40)/b5-4+/t14-,18-,19-,20?,24-/m1/s1KFWWCMJSYSSPSK-BOGFJHSMSA-N(2R)-4-({[({[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-4-hydroxy-3-(phosphonooxy)oxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)-N-[2-({2-[(2E)-but-2-enoylsulfanyl]ethyl}-C-hydroxycarbonimidoyl)ethyl]-2-hydroxy-3,3-dimethylbutanimidic acid835.608835.141423115-2.369(2R)-4-[({[(2R,3S,4R,5R)-5-(6-aminopurin-9-yl)-4-hydroxy-3-(phosphonooxy)oxolan-2-yl]methoxy(hydroxy)phosphoryl}oxy(hydroxy)phosphoryl)oxy]-N-[2-({2-[(2E)-but-2-enoylsulfanyl]ethyl}-C-hydroxycarbonimidoyl)ethyl]-2-hydroxy-3,3-dimethylbutanimidic acid0-4FDB0227922-butenoyl-coa;2-butenoyl-coenzyme a;But-2-enoyl-coa;But-2-enoyl-coenzyme a;Crotonyl-coenzyme a;S-but-2-enoylcoenzyme a;Trans-but-2-enoyl-coa;Trans-but-2-enoyl-coenzyme aPW_C001345CrtylCA58841083352269452761037000161823615177256133782811121202814061207914071229461201233811191256204791271475011142Acetoacetyl-CoAHMDB0001484Acetoacetyl-CoA is an intermediate in the metabolism of Butanoate.

It also acts as a biological acetylating agent.72-89-9C0002444449315351ACETYL-COA392413CC(=O)SCCNC(=O)CCNC(=O)[C@H](O)C(C)(C)COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H]([C@H](O)[C@@H]1OP(O)(O)=O)N1C=NC2=C1N=CN=C2NC23H38N7O17P3SInChI=1S/C23H38N7O17P3S/c1-12(31)51-7-6-25-14(32)4-5-26-21(35)18(34)23(2,3)9-44-50(41,42)47-49(39,40)43-8-13-17(46-48(36,37)38)16(33)22(45-13)30-11-29-15-19(24)27-10-28-20(15)30/h10-11,13,16-18,22,33-34H,4-9H2,1-3H3,(H,25,32)(H,26,35)(H,39,40)(H,41,42)(H2,24,27,28)(H2,36,37,38)/t13-,16-,17-,18+,22-/m1/s1ZSLZBFCDCINBPY-ZSJPKINUSA-N{[(2R,3S,4R,5R)-2-({[({[(3R)-3-[(2-{[2-(acetylsulfanyl)ethyl]carbamoyl}ethyl)carbamoyl]-3-hydroxy-2,2-dimethylpropoxy](hydroxy)phosphoryl}oxy)(hydroxy)phosphoryl]oxy}methyl)-5-(6-amino-9H-purin-9-yl)-4-hydroxyoxolan-3-yl]oxy}phosphonic acid809.571809.125773051-2.279acetyl-CoA0-4FDB022491Ac-coa;Ac-coenzyme a;Ac-s-coa;Ac-s-coenzyme a;Acetyl coenzyme-a;Acetyl-coa;Acetyl-coenzyme a;Acetyl-s-coa;Acetyl-s-coenzyme a;Acetylcoenzyme-a;S-acetate coa;S-acetate coenzyme a;S-acetyl coenzyme a;Accoa;Acetyl coenzyme a;S-acetyl-coa;S-acetyl-coenzyme a;Acetylcoenzyme aPW_C000940Ac-CoA21343858842324162244652896173340114840145278103547612457331086025155607716163861647017869231607106163729119874602228245151827721012582226130122994261531577121133772911117756211277706132779941157835513478433334800073688063411980663376901241701199534061201454051203041221206324071224174081226263841227431201229591351231371181249863741252001211253434791255074781256332971265644821265724811267784801268865011270442091273942051276653881281375021281452061283743911099Coenzyme AHMDB0001423Coenzyme A (CoA, CoASH, or HSCoA) is a coenzyme notable for its role in the synthesis and oxidization of fatty acids and the oxidation of pyruvate in the citric acid cycle. It is adapted from beta-mercaptoethylamine, panthothenate, and adenosine triphosphate. It is also a parent compound for other transformation products, including but not limited to, phenylglyoxylyl-CoA, tetracosanoyl-CoA, and 6-hydroxyhex-3-enoyl-CoA. Coenzyme A is synthesized in a five-step process from pantothenate and cysteine. In the first step pantothenate (vitamin B5) is phosphorylated to 4'-phosphopantothenate by the enzyme pantothenate kinase (PanK, CoaA, CoaX). In the second step, a cysteine is added to 4'-phosphopantothenate by the enzyme phosphopantothenoylcysteine synthetase (PPC-DC, CoaB) to form 4'-phospho-N-pantothenoylcysteine (PPC). In the third step, PPC is decarboxylated to 4'-phosphopantetheine by phosphopantothenoylcysteine decarboxylase (CoaC). In the fourth step, 4'-phosphopantetheine is adenylylated to form dephospho-CoA by the enzyme phosphopantetheine adenylyl transferase (CoaD). Finally, dephospho-CoA is phosphorylated using ATP to coenzyme A by the enzyme dephosphocoenzyme A kinase (CoaE). Since coenzyme A is, in chemical terms, a thiol, it can react with carboxylic acids to form thioesters, thus functioning as an acyl group carrier. CoA assists in transferring fatty acids from the cytoplasm to the mitochondria. A molecule of coenzyme A carrying an acetyl group is also referred to as acetyl-CoA. When it is not attached to an acyl group, it is usually referred to as 'CoASH' or 'HSCoA'. Coenzyme A is also the source of the phosphopantetheine group that is added as a prosthetic group to proteins such as acyl carrier proteins and formyltetrahydrofolate dehydrogenase. Acetyl-CoA is an important molecule itself. It is the precursor to HMG CoA which is a vital component in cholesterol and ketone synthesis. Furthermore, it contributes an acetyl group to choline to produce acetylcholine in a reaction catalysed by choline acetyltransferase. Its main task is conveying the carbon atoms within the acetyl group to the citric acid cycle to be oxidized for energy production (Wikipedia).85-61-0C0001068161146900CO-A6557CC(C)(COP(O)(=O)OP(O)(=O)OC[C@H]1O[C@H]([C@H](O)[C@@H]1OP(O)(O)=O)N1C=NC2=C1N=CN=C2N)[C@@H](O)C(=O)NCCC(=O)NCCSC21H36N7O16P3SInChI=1S/C21H36N7O16P3S/c1-21(2,16(31)19(32)24-4-3-12(29)23-5-6-48)8-41-47(38,39)44-46(36,37)40-7-11-15(43-45(33,34)35)14(30)20(42-11)28-10-27-13-17(22)25-9-26-18(13)28/h9-11,14-16,20,30-31,48H,3-8H2,1-2H3,(H,23,29)(H,24,32)(H,36,37)(H,38,39)(H2,22,25,26)(H2,33,34,35)/t11-,14-,15-,16+,20-/m1/s1RGJOEKWQDUBAIZ-IBOSZNHHSA-N{[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-4-hydroxy-2-({[hydroxy({hydroxy[(3R)-3-hydroxy-2,2-dimethyl-3-({2-[(2-sulfanylethyl)carbamoyl]ethyl}carbamoyl)propoxy]phosphoryl}oxy)phosphoryl]oxy}methyl)oxolan-3-yl]oxy}phosphonic acid767.534767.115208365-2.2210coenzyme A0-4FDB022614Acetoacetyl coenzyme a sodium salt;Coa;Coa hydrate;Coa-sh;Coash;Coenzyme a;Coenzyme a hydrate;Coenzyme a-sh;Coenzyme ash;Coenzymes a;Depot-zeel;Propionyl coa;Propionyl coenzyme a;S-propanoate;S-propanoate coa;S-propanoate coenzyme a;S-propanoic acid;S-propionate coa;S-propionate coenzyme a;Zeel;[(2r,3s,4r,5r)-5-(6-amino-9h-purin-9-yl)-4-hydroxy-3-(phosphonooxy)tetrahydrofuran-2-yl]methyl 3-hydroxy-4-({3-oxo-3-[(2-sulfanylethyl)amino]propyl}amino)-2,2-dimethyl-4-oxobutyl dihydrogen diphosphatePW_C001099CoA21143868845387922892172407592414224595281329286231334211335118461810462958484214486554487965232102524710452801035477124573410857771016023155607516163841646817869301606961162697319970831887108163729319873472107458222822915190812269090224912417092151951301329915318249254884942616315769072937711913377222134772303297729211177550132775553347756311277633336776721297799611578047332780563507841333578567130792593337997433180005368806201188062737480635119806653769382838293834383986742881105553891105613901158423991158473981199514061201474051202313841203051221206344071207621171214061231214214331215211251216664291216824081217144141224044221227411201229041211229601351239654471239794681240791361242204641242654501249743751253414791255094781255794801255924841256342971260844811265494911265604821267463001268845011270462091271093911273012051275402061276673881281215081281335021283403957691(S)-2,3,4,5-Tetrahydropiperidine-2-carboxylateHMDB0012130(S)-2,3,4,5-Tetrahydropiperidine-2-carboxylate is a cyclic intermediate in lysine degradation.

Diatomic oxygen gas constitutes 20.9% of the volume of air. All major classes of structural molecules in living organisms, such as proteins, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that comprise animal shells, teeth, and bone. Oxygen in the form of O2 is produced from water by cyanobacteria, algae and plants during photosynthesis and is used in cellular respiration for all living organisms. Green algae and cyanobacteria in marine environments provide about 70% of the free oxygen produced on earth and the rest is produced by terrestrial plants. Oxygen is used in mitochondria to help generate adenosine triphosphate (ATP) during oxidative phosphorylation. For animals, a constant supply of oxygen is indispensable for cardiac viability and function. To meet this demand, an adult human, at rest, inhales 1.8 to 2.4 grams of oxygen per minute. This amounts to more than 6 billion tonnes of oxygen inhaled by humanity per year. At a resting pulse rate, the heart consumes approximately 8-15 ml O2/min/100 g tissue. This is significantly more than that consumed by the brain (approximately 3 ml O2/min/100 g tissue) and can increase to more than 70 ml O2/min/100 g myocardial tissue during vigorous exercise. As a general rule, mammalian heart muscle cannot produce enough energy under anaerobic conditions to maintain essential cellular processes; thus, a constant supply of oxygen is indispensable to sustain cardiac function and viability. However, the role of oxygen and oxygen-associated processes in living systems is complex, and they and can be either beneficial or contribute to cardiac dysfunction and death (through reactive oxygen species). Reactive oxygen species (ROS) are a family of oxygen-derived free radicals that are produced in mammalian cells under normal and pathologic conditions. Many ROS, such as the superoxide anion (O2-)and hydrogen peroxide (H2O2), act within blood vessels, altering mechanisms mediating mechanical signal transduction and autoregulation of cerebral blood flow. Reactive oxygen species are believed to be involved in cellular signaling in blood vessels in both normal and pathologic states. The major pathway for the production of ROS is by way of the one-electron reduction of molecular oxygen to form an oxygen radical, the superoxide anion (O2-). Within the vasculature there are several enzymatic sources of O2-, including xanthine oxidase, the mitochondrial electron transport chain, and nitric oxide (NO) synthases. Studies in recent years, however, suggest that the major contributor to O2- levels in vascular cells is the membrane-bound enzyme NADPH-oxidase. Produced O2- can react with other radicals, such as NO, or spontaneously dismutate to produce hydrogen peroxide (H2O2). In cells, the latter reaction is an important pathway for normal O2- breakdown and is usually catalyzed by the enzyme superoxide dismutase (SOD). Once formed, H2O2 can undergo various reactions, both enzymatic and nonenzymatic. The antioxidant enzymes catalase and glutathione peroxidase act to limit ROS accumulation within cells by breaking down H2O2 to H2O. Metabolism of H2O2 can also produce other, more damaging ROS. For example, the endogenous enzyme myeloperoxidase uses H2O2 as a substrate to form the highly reactive compound hypochlorous acid. Alternatively, H2O2 can undergo Fenton or Haber-Weiss chemistry, reacting with Fe2+/Fe3+ ions to form toxic hydroxyl radicals (-.OH).

It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper, but has also found use as a disinfectant and as an oxidizer. Hydrogen peroxide in the form of carbamide peroxide is widely used for tooth whitening (bleaching), both in professionally- and in self-administered products. Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in host defense and oxidative biosynthetic reactions. In addition there is growing evidence that at low levels, H2O2 also functions as a signaling agent, particularly in higher organisms. H2O2 has increasingly been viewed as an important cellular signaling agent in its own right, capable of modulating both contractile and growth-promoting pathways with more far-reaching effects. Due to the accumulation of hydrogen peroxide in the skin of patients with the depigmentation disorder vitiligo, the human epidermis cannot have the normal capacity for autocrine synthesis, transport and degradation of acetylcholine as well as the muscarinic (m1-m5) and nicotinic signal transduction in keratinocytes and melanocytes. Accumulating evidence suggests that hydrogen peroxide (H(2)O(2)) plays an important role in cancer development. Experimental data have shown that cancer cells produce high amounts of H(2)O(2). An increase in the cellular levels of H(2)O(2) has been linked to several key alterations in cancer, including DNA alterations, cell proliferation, apoptosis resistance, metastasis, angiogenesis and hypoxia-inducible factor 1 (HIF-1) activation.

These are nucleotides containing a flavin moiety. Flavin is a compound that contains the tricyclic isoalloxazine ring system, which bears 2 oxo groups at the 2- and 4-positions. FAD is a drug which is used to treat eye diseases caused by vitamin b2 deficiency, such as keratitis and blepharitis. FAD is slightly soluble (in water) and a moderately acidic compound (based on its pKa). FAD has been found in human liver and muscle tissues, and has also been detected in multiple biofluids, such as feces and blood. Within the cell, FAD is primarily located in the cytoplasm, mitochondria, endoplasmic reticulum and peroxisome. FAD exists in all living organisms, ranging from bacteria to humans. In humans, FAD is involved in the risedronate action pathway, the ibandronate action pathway, the valine, leucine and isoleucine degradation pathway, and the pyrimidine metabolism pathway. FAD is also involved in several metabolic disorders, some of which include the oncogenic action OF L-2-hydroxyglutarate in hydroxygluaricaciduria pathway, gaba-transaminase deficiency, 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency, and the saccharopinuria/hyperlysinemia II pathway. FAD is a condensation product of riboflavin and adenosine diphosphate. The coenzyme of various aerobic dehydrogenases, e.g., D-amino acid oxidase and L-amino acid oxidase.

Carbon dioxide is produced during respiration by all animals, fungi and microorganisms that depend on living and decaying plants for food, either directly or indirectly. It is, therefore, a major component of the carbon cycle. Additionally, carbon dioxide is used by plants during photosynthesis to make sugars which may either be consumed again in respiration or used as the raw material to produce polysaccharides such as starch and cellulose, proteins and the wide variety of other organic compounds required for plant growth and development. When inhaled at concentrations much higher than usual atmospheric levels, it can produce a sour taste in the mouth and a stinging sensation in the nose and throat. These effects result from the gas dissolving in the mucous membranes and saliva, forming a weak solution of carbonic acid. Carbon dioxide is used by the food industry, the oil industry, and the chemical industry. Carbon dioxide is used to produce carbonated soft drinks and soda water. Traditionally, the carbonation in beer and sparkling wine comes about through natural fermentation, but some manufacturers carbonate these drinks artificially.124-38-9C0001128016526274O=C=OCO2InChI=1S/CO2/c2-1-3CURLTUGMZLYLDI-UHFFFAOYSA-Nmethanedione44.009543.9898292440.630carbon dioxide00DBMET00423FDB014084Carbon oxide;Carbon-12 dioxide;Carbonic acid anhydride;Carbonic acid gas;Carbonic anhydride;[co2];Co2;E 290;E-290;E290;R-744PW_C001316CO250812112044480135031864036773169520806511334316384917452255117314470528310353201115750108577110159681006026155607816164711786637107692219070171607035163706118871632057308198733321374612227530210821522582231519158249118492771190817012464226126882904262631543523318769942937712213377170132774703337773911277750129777633417807713478405356784273347894133179227130800083688067511980717135948363841132913911155491211199544061200891221201554071203644121205564141208334191209221241209914081212841251215053831227441201230114461231904501234184551234891181235563741238551361240633981253444791254602971255164811258244901258702991259314821262804801268875011270522061272775071273313881273905021060Thiamine pyrophosphateHMDB0001372Thiamine pyrophosphate is the active form of thiamine, and it serves as a cofactor for several enzymes involved primarily in carbohydrate catabolism. The enzymes are important in the biosynthesis of a number of cell constituents, including neurotransmitters, and for the production of reducing equivalents used in oxidant stress defenses and in biosyntheses and for synthesis of pentoses used as nucleic acid precursors. The chemical structure of TPP is that of an aromatic methylaminopyrimidine ring, linked via a methylene bridge to a methylthiazolium ring with a pyrophosphate group attached to a hydroxyethyl side chain. In non-enzymatic model studies it has been demonstrated that the thiazolium ring can catalyse reactions which are similar to those of TPP-dependent enzymes but several orders of magnitude slower. Using infrared and NMR spectrophotometry it has been shown that the dissociation of the proton from C2 of the thiazolium ring is necessary for catalysis; the abstraction of the proton leads to the formation of a carbanion (ylid) with the potential for a nucleophilic attack on the carbonyl group of the substrate. In all TPP-dependent enzymes the abstraction of the proton from the C2 atom is the first step in catalysis, which is followed by a nucleophilic attack of this carbanion on the substrate. Subsequent cleavage of a C-C bond releases the first product with formation of a second carbanion (2-greek small letter alpha-carbanion or enamine). The formation of this 2-greek small letter alpha-carbanion is the second feature of TPP catalysis common to all TPP-dependent enzymes. Depending on the enzyme and the substrate(s), the reaction intermediates and products differ. Methyl-branched fatty acids, as phytanic acid, undergo peroxisomal beta-oxidation in which they are shortened by 1 carbon atom. This process includes four steps: activation, 2-hydroxylation, thiamine pyrophosphate dependent cleavage and aldehyde dehydrogenation. In the third step, 2-hydroxy-3-methylacyl-CoA is cleaved in the peroxisomal matrix by 2-hydroxyphytanoyl-CoA lyase (2-HPCL), which uses thiamine pyrophosphate (TPP) as cofactor. The thiamine pyrophosphate dependence of the third step is unique in peroxisomal mammalian enzymology. Human pathology due to a deficient alpha-oxidation is mostly linked to mutations in the gene coding for the second enzyme of the sequence, phytanoyl-CoA hydroxylase (EC 1.14.11.18).

(PMID:8957191). Lipoamide is a trivial name for 6,8-dithiooctanoic amide. It is 6,8-dithiooctanoic acid's functional form where the carboxyl group is attached to protein (or any other amine) by an amide linkage (containing -NH2) to an amino group. Lipoamide forms a thioester bond, oxidizing the disulfide bond, with acetaldehyde (pyruvate after it has been decarboxylated). It then transfers the acetaldehyde group to CoA which can then continue in the TCA cycle. (Wikipedia). Lipoamide is an intermediate in glycolysis/gluconeogenesis, citrate cycle (TCA cycle), alanine, aspartate and pyruvate metabolism, and valine, leucine and isoleucine degradation (KEGG:C00248). It is generated from dihydrolipoamide via the enzyme dihydrolipoamide dehydrogenase (EC:1.8.1.4) and then converted to S-glutaryl-dihydrolipoamide via the enzyme oxoglutarate dehydrogenase (EC:1.2.4.2).940-69-2C0024886317460LIPOAMIDE840NC(=O)CCCCC1CCSS1C8H15NOS2InChI=1S/C8H15NOS2/c9-8(10)4-2-1-3-7-5-6-11-12-7/h7H,1-6H2,(H2,9,10)FCCDDURTIIUXBY-UHFFFAOYSA-N5-(1,2-dithiolan-3-yl)pentanamide205.341205.059505487-3.311lipoamide00FDB0223401,2-dithiolane-3-pentanamide;5-(1,2-dithiolan-3-yl)-pentanamide;5-(1,2-dithiolan-3-yl)pentanamide;5-(1,2-dithiolan-3-yl)valeramide;5-(dithiolan-3-yl)valeramide;Dl-lipoamide;Dl-6-thioctic amide;Lipamide;Lipoacin;Lipoamid;Lipoicin;Lipozyme;Lypoaran;Pathoclon;Thioami;Thioctamid;Thioctamide;Thioctic acid amide;Thioctic acid amide (jan);Thiotomin;Ticolin;Vitamin n;Alpha-lipoate;Alpha-lipoic acid;Alpha-lipoic acid amide;A-lipoate amide;A-lipoic acid amide;Alpha-lipoate amide;α-lipoate amide;α-lipoic acid amide;Thioctate amidePW_C000769Lipoamd202410733173424667853671036029155608116163891647417874642227712513378286112791731328001136811995740612080340712153512412274712012338911912409311812534747912607848112689050112753420669electron-transfer flavoproteinCompoundPW_EC0000695086ChEBIETF70Reduced electron-transfer flavoproteinCompoundPW_EC0000705086ChEBIRETF14290Alpha-aminoadipic semialdehyde synthase, mitochondrialQ99K67

Gsr121.8.1.7771301337902911214152Cationic amino acid transporter 2P18581
Isoform 1 functions as low-affinity, high capacity permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine). Isoform 2 also functions as permease that mediates the transport of the cationic amino acids (arginine, lysine and ornithine), but it has much higher affinity for arginine than isoform 1. May play a role in classical or alternative activation of macrophages via its role in arginine transport.
