EC 1.3.8.8

Names

Accepted name:
long-chain-acyl-CoA dehydrogenase
Other names:
long-chain acyl-coenzyme A dehydrogenase
palmitoyl-CoA dehydrogenase
palmitoyl-coenzyme A dehydrogenase
long-chain-acyl-CoA:(acceptor) 2,3-oxidoreductase
ACADL (gene name)
Systematic name:
long-chain-acyl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase

Reaction

Cofactor

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 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 [2]. 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 [4]. cf. EC 1.3.8.1, short-chain acyl-CoA dehydrogenase, EC 1.3.8.8, medium-chain acyl-CoA dehydrogenase, and EC 1.3.8.9, very-long-chain acyl-CoA dehydrogenase.
