2-Ketoglutarate Dehydrogenase Complex Deficiency

Mus musculus
2-Ketoglutarate dehydrogenase complex deficiency, also known as alpha-ketoglutarate dehydrogenase deficiency or oxoglutaric aciduria, is an autosomal recessive disorder of the Krebs cycle caused by a defective oxoglutarate dehydrogenase complex (OGDC). OGDC catalyzes the conversion of 2-ketoglutarate into succinyl-CoA. This disorder is characterized by a large accumulation of 2-ketoglutarate in the urine. Symptoms of the disorder include opisthotonus, ataxia, developmental delay, and seizures.

2-Hydroxyglutric Aciduria (D and L Form)

Mus musculus
L-2-Hydroxyglutaric Aciduria (D-2-Hydroxyglutaric Aciduria ) is an autosomal recessive disease caused by a mutation in the L2HGDH gene which codes for L-2-Hydroxygluarate dehydrogenase. A deficiency in this enzyme results in accumulation of L-2-Hydroxyglutaric acid in plasma, spinal fluid, and urine; and L-lysine in plasma and spinal fluid. Symptoms, which present at birth, include ataxia, hypotonia, mental retardation, and seizures. Premature death often results. D-2-Hydroxyglutaric Aciduria is an autosomal recessive disease caused by a mutation in the D2HGDH gene which does for D-2-Hydroxygluarate dehydrogenase. A deficiency in this enzyme results in accumulation of D-2-Hydroxyglutaric acid in plasma, spinal fluid, and urine; oxoglutaric acid in urine; and gabba-aminobutyric acid in spinal fluid. Symptoms, which present at birth, include ataxia, hypotonia, mental retardation, and seizures. Premature death often results.

2-Heptyl-3-hydroxy-quinolone (PQS) biosynthesis

Pseudomonas aeruginosa
2-Heptyl-3-hydroxy-4-quinolone (PQS) is key to quorum sensing and virulence in bacteria like Pseudomonas aeruginosa PAO1. This biosynthesis begins with the precursor chorismate, which is derived from the shikimate pathway during the biosynthesis of aromatic amino acids e.g., phenylalanine, tyrosine and tryptophan. Chorismate is converted into anthranilate by anthranilate synthase, then into Anthraniloyl-CoA. The subsequent steps involve the action of enzymes 3-oxoacyl-ACP synthase, thioesterase PqsE, and 2-heptyl-4(1H)-quinolone synthase, which facilitate the conversion of Anthraniloyl-CoA to 2-heptyl-4(1H)-quinolone (HHQ), the direct precursor of PQS. Finally, 2-heptyl-3-hydroxy-4(1H)-quinolone synthase hydroxylates HHQ to produce PQS thus linking primary metabolism to secondary metanolism, significant to microbial communication and adaptation.

2-Aminoadipic 2-Oxoadipic Aciduria

Rattus norvegicus
2-Aminoadipic 2-oxoadipic aciduria is a disorder of lysine metabolism caused by a defective DHTKD1 gene. DHTKD1 is predicted to code for a component of a supercomplex similar to the 2-oxoglutarate dehydrogenase complex (OGDHc) which catalyzes the conversion of 2-oxoadipate into glutaryl-CoA. This disease is characterized by a large accumulation of 2-oxoadipate and 2-hydroxyadipate in the urine. Symptoms of the disease include mild to severe intellectual disability, developmental delay, ataxia, muscular hypotonia, and epilepsy. However, most cases are asymptomatic.
