EC 1.3.8.8     
Accepted name: long-chain acyl-CoA dehydrogenase
Reaction: a long-chain acyl-CoA + electron-transfer flavoprotein = a long-chain trans-2,3-dehydroacyl-CoA + reduced electron-transfer flavoprotein
Glossary: a long-chain acyl-CoA = an acyl-CoA thioester where the acyl chain contains 13 to 22 carbon atoms.
Other name(s): palmitoyl-CoA dehydrogenase; palmitoyl-coenzyme A dehydrogenase; long-chain acyl-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
Comments: Contains a tightly-bound FAD cofactor. 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.
