PW000210 View Pathway	disease Vitamin A Deficiency Homo sapiens Vitamin A deficiency can be caused by many causes. A defect in the BCMO1 gene which codes for beta,beta-carotene 15,15’-monooxygenase is one of them. Beta,beta-carotene 15,15’-monooxygenase catalyzes the chemical reaction where the two substrates are beta-carotene and O2, whereas its product is retinal. A defect in this enzyme results in decrease of levels of retinal and vitamin A in serum; Signs and symptoms include night blindness, poor adaptation to darkness, dry skin and hair.

PW002486 View Pathway	metabolic Vitamin B1/Thiamine Metabolism Saccharomyces cerevisiae The biosynthesis of thiamine begins with pyrithiamine reacting with thiaminase 2 resulting in the release of 4-Amino-5-hydroxymethyl-2-methylpyrimidine. The latter compound reacts with a hydroxymethylpyrimidine/phosphomethylpyrimidine kinase resulting in the release of 4-amino-2-methyl-5-phosphomethylpyrimidine. The latter compound reacts with a hydroxymethylpyrimidine/phosphomethylpyrimidine kinase resulting in the release of 2-Methyl-4-amino-5-hydroxymethylpyrimidine diphosphate. The latter compound reacts with 4-methyl-5-(2-phosphonooxyethyl)thiazole, a product of oxythiamine metabolism, through a Thiamine biosynthetic bifunctional enzyme resultin in the release of a Thiamine monophosphate. The latter compound is phosphatased through a acid phosphatase complex resulting in the release of thiamine. The latter compound is phosphorylated through a thiamin pyrophosphokinase resulting in the release of thiamine pyrophosphate.

PW002488 View Pathway	metabolic Vitamin B6 Saccharomyces cerevisiae Vitamin B6 belongs to the vitamin B complex group and is water-soluble. The active form is Pyridoxal phosphate (PLP) which acts as a cofactor for various essential enzymes in reactions including: amino acid metabolism, transamination, deamination, and decarboxylation. Other forms of the vitamin include: pyridoxine (PN), pyridoxine 5’-phosphate (PNP), pyridoxal (PL), pyridoxamine (PM), pyridoxamine 5’-phosphate (PMP), and 4-pyridoxic acid (PA). Most animals are unable to synthesize the vitamin while most bacteria are able too. Some organisms also import the vitamin to supplement or augment biosynthesis. S. cerevisiae has transporter Tpn1p on the plasma membrane to import vitamin B6. It transports mostly PN, a precursor of PLP, but also PM and PL. Vitamin B6 is also an antioxidant to provide protection against reactive oxygen species. It has been shown that vitamin B6 synthesis is increased in response to cell stress.

PW000891 View Pathway	metabolic Vitamin B6 Metabolism Escherichia coli Vitamin B6 metabolism in bacteria involves the biosynthesis and utilization of various forms of Vitamin B6, primarily pyridoxal 5'-phosphate (PLP), the active form of the vitamin. Bacteria can synthesize Vitamin B6 through two main pathways: the de novo DXP-independent pathway (pyridoxal phosphate biosynthesis I) and the DXP-dependent pathway. In the de novo pathway, key enzymes like Pdx1 and Pdx2 convert intermediates into pyridoxine 5'-phosphate (PNP), which is then oxidized to PLP by the enzyme pyridoxine phosphate oxidase (PdxH). PLP acts as a cofactor for various enzymes involved in amino acid metabolism, including transaminases, decarboxylases, and racemases.Bacteria rely on PLP for critical cellular processes, including amino acid metabolism, stress response, and protection against oxidative damage.

PW088352 View Pathway	metabolic Vitamin B6 Metabolism Rattus norvegicus As is commonly known there are many vitamins, the vitamin B complex group being one of the most well known. An important vitamin B complex group vitamin is vitamin B6, which is water-soluble. Moreover, this vitamin comes in various forms, one of which is an active form, known by the name pyridoxal phosphate or PLP. PLP serves as cofactor in a variety of reactions including from amino acid metabolism, (in particular in reactions such as transamination, deamination, and decarboxylation). To complicate matters however, there are in fact seven alternate forms of this same vitamin. These include pyridoxine (PN), pyridoxine 5’-phosphate (PNP), pyridoxal (PL), pyridoxamine (PM), pyridoxamine 5’-phosphate (PMP), 4-pyridoxic acid (PA), and the aforementioned pyridoxal 5’-phosphate (PLP). One of these forms, PA, is in fact a catabolite whose presence is found in excreted urine. For a person to absorb some of these active forms of vitamin B6 such as PLP or PMP they must first be dephosphorylized. This done via an alkaline enzyme phosphatase. There are a wide variety of biproducts from the metabolism in question, most of which find there ways into the urine and from there are excreted. One such biproduct is 4-pyridoxic acid. In fact this last biproduct is found in such large quantities that estimates of vitamin B6 metabolism birproducts show that 4-pyridoxic acid is as much as 40-60% of all the biproducts.Of course, it is not the only product of metabolism. Others include,include pyridoxal, pyridoxamine, and pyridoxine.
