Accepted name: long-chain-3-hydroxyacyl-CoA dehydrogenase
Reaction: a long-chain (S)-3-hydroxyacyl-CoA + NAD+ = a long-chain 3-oxoacyl-CoA + NADH + H+
Glossary: a long-chain acyl-CoA = an acyl-CoA thioester where the acyl chain contains 13 to 22 carbon atoms.
Other name(s): β-hydroxyacyl-CoA dehydrogenase; long-chain 3-hydroxyacyl coenzyme A dehydrogenase; 3-hydroxyacyl-CoA dehydrogenase; LCHAD
Systematic name: long-chain-(S)-3-hydroxyacyl-CoA:NAD+ oxidoreductase
Comments: This enzyme was purified from the mitochondrial inner membrane. The enzyme has a preference for long-chain substrates, and activity with a C16 substrate was 6- to 15-fold higher than with a C4 substrate (cf. EC 3-hydroxyacyl-CoA dehydrogenase).
