EC 1.3.8.9

Accepted name: very-long-chain acyl-CoA dehydrogenase

Reaction: a very-long-chain acyl-CoA + electron-transfer flavoprotein = a very-long-chain trans-2,3-dehydroacyl-CoA + reduced electron-transfer flavoprotein

Glossary: a very-long-chain acyl-CoA = an acyl-CoA thioester where the acyl chain contains 23 or more carbon atoms.

Other name(s): ACADVL (gene name).

Systematic name: very-long-chain acyl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase

Comments: Contains FAD as prosthetic group. One of several enzymes that catalyse the first step in fatty acids β-oxidation. The enzyme is most active toward long-chain acyl-CoAs such as C14, C16 and C18, but is also active with very-long-chain acyl-CoAs up to 24 carbons. It shows no activity for substrates of less than 12 carbons. Its specific activity towards palmitoyl-CoA is more than 10-fold that of the long-chain acyl-CoA dehydrogenase [1]. cf. EC 1.3.8.1, short-chain acyl-CoA dehydrogenase, EC 1.3.8.7, medium-chain acyl-CoA dehydrogenase, and EC 1.3.8.8, long-chain acyl-CoA dehydrogenase.
