ID 1.3.8.8 DE long-chain-acyl-CoA dehydrogenase. CA a long-chain 2,3-saturated fatty acyl-CoA + H(+) + oxidized [electron- CA transfer flavoprotein] = a long-chain (2E)-enoyl-CoA + reduced [electron- CA transfer flavoprotein]. CC -!- One of several enzymes that catalyze the first step in fatty acids CC beta-oxidation. CC -!- The enzyme from pig liver can accept substrates with acyl chain CC lengths of 6 to at least 16 carbon atoms. CC -!- The highest activity was found with C12, and the rates with C8 and CC C16 were 80% and 70%, respectively. CC -!- The enzyme from rat can accept substrates with C8-C22. CC -!- It is most active with C14 and C16, and has no activity with C4, CC C6 or C24. cf. EC 1.3.8.1, EC 1.3.8.8 and EC 1.3.8.9. CC -!- Formerly EC 1.3.99.3 and EC 1.3.99.13.
