Name: Crotonoyl-CoA
Description:Crotonoyl-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.: corresponding to palmitoyl, branched chain, and pristanoyl, respectively, in the peroxisomal fatty acid beta-oxidation, producing hydrogen peroxide. It is also a substrate of a group of enzymes called acyl-Coenzyme A dehydrogenase (E.C.:1.3.99-, including, in the metabolism of fatty acids. In addition, crotonoyl-CoA is the substrate of enoyl coenzyme A hydratase (E.C. 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.:, glutaconyl-CoA decarboxylase (E.C.:, vinylacetyl-CoA delta-isomerase (E.C.:, and trans-2-enoyl-CoA reductase (NAD+) (E.C.: In lysine degradation and tryptophan metabolism, crotonoyl CoA is produced by glutaryl-Coenzyme A dehydrogenase (E.C.: lysine and tryptophan metabolic pathway.
