Common_NameCrotonoyl-CoA
DescriptionCrotonoyl-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.
