IntEnz Enzyme Nomenclature
EC 1.3.8.7
Names
acyl coenzyme A dehydrogenase [ambiguous]
acyl dehydrogenase [ambiguous]
fatty-acyl-CoA dehydrogenase [ambiguous]
acyl CoA dehydrogenase [ambiguous]
general acyl CoA dehydrogenase [ambiguous]
medium-chain acyl-coenzyme A dehydrogenase
acyl-CoA:(acceptor) 2,3-oxidoreductase [ambiguous]
ACADM (gene name)
Reaction
- a medium-chain acyl-CoA + electron-transfer flavoprotein = a medium-chain trans-2,3-dehydroacyl-CoA + reduced electron-transfer flavoprotein
Comments:
Contains FAD as prosthetic group. One of several enzymes that catalyse the first step in fatty acids β-oxidation. The enzyme from pig liver can accept substrates with acyl chain lengths of 4 to 16 carbon atoms, but is most active with C8 to C12 compounds [2]. The enzyme from rat does not accept C16 at all and is most active with C6-C8 compounds [4]. cf. EC 1.3.8.1, short-chain acyl-CoA dehydrogenase, EC 1.3.8.8, long-chain acyl-CoA dehydrogenase, and EC 1.3.8.9, very-long-chain acyl-CoA dehydrogenase.
