Enzyme Commission Summary:
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 6 to at least 16 carbon atoms. The highest activity was found with C12, and the rates with C8 and C16 were 80 and 70%, respectively [Hauge56]. The enzyme from rat can accept substrates with C8-C22. It is most active with C14 and C16, and has no activity with C4, C6 or C24 [Ikeda85]. cf. EC 126.96.36.199, short-chain acyl-CoA dehydrogenase, EC 188.8.131.52, medium-chain acyl-CoA dehydrogenase, and EC 184.108.40.206, very-long-chain acyl-CoA dehydrogenase.
