Common_Nametrans-2-Hexenoyl-CoA
Descriptiontrans-Hexenoyl-CoA is an intermediate in fatty acid metabolism. beta-oxidation occurs in both mitochondria and peroxisomes. mitochondria catalyze the beta-oxidation of the bulk of short-, medium-, and long-chain fatty acids derived from diet, and this pathway constitutes the major process by which fatty acids are oxidized to generate energy. Peroxisomes are involved in the beta-oxidation chain shortening of long-chain and very-long-chain fatty acyl-coenzyme (CoAs), long-chain dicarboxylyl-CoAs, the CoA esters of eicosanoids, 2-methyl-branched fatty acyl-CoAs, and the CoA esters of the bile acid intermediates di- and trihydroxycoprostanoic acids, and in the process they generate H2O2. Long-chain and very-long-chain fatty acids (VLCFAs) are also metabolized by the cytochrome P450 CYP4A omega-oxidation system to dicarboxylic acids that serve as substrates for peroxisomal beta-oxidation. The peroxisomal beta-oxidation system consists of (a) a classical peroxisome proliferator-inducible pathway capable of catalyzing straight-chain acyl-CoAs by fatty acyl-CoA oxidase, L-bifunctional protein, and thiolase, and (b) a second noninducible pathway catalyzing the oxidation of 2-methyl-branched fatty acyl-CoAs by branched-chain acyl-CoA oxidase (pristanoyl-CoA oxidase/trihydroxycoprostanoyl-CoA oxidase), D-bifunctional protein, and sterol carrier protein (SCP)x. trans-Hexenoyl-CoA is the substrate of the enzymes enoyl-coenzyme A reductase, acyl-CoA oxidase [EC 1.3.99.2-1.3.3.6], acyl-CoA dehydrogenase, long-chain-acyl-CoA dehydrogenase [EC 1.3.99.3-1.3.99.13], and Oxidoreductases [EC 1.3.99.-]; trans-Hexenoyl-CoA is an intermediate in fatty acid elongation in mitochondria, being the substrate of the enzymes enoyl-CoA hydratase and long-chain-enoyl-CoA hydratase [EC 4.2.1.17-4.2.1.74].
