A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.3.8.1

Accepted Name
Short-chain acyl-CoA dehydrogenase.
Alternative Name(s)
Butanoyl-CoA dehydrogenase.
Butyryl dehydrogenase.
Short-chain acyl CoA dehydrogenase.
Unsaturated acyl-CoA reductase.
Reaction catalysed
A short-chain acyl-CoA + electron-transfer flavoprotein <=> a short-chain trans-2,3-dehydroacyl-CoA + reduced electron-transfer flavoprotein
Cofactor(s)
FAD.
Comment(s)
  • One of several enzymes that catalyze the first step in fatty acids beta-oxidation.
  • The enzyme catalyzes the oxidation of saturated short-chain acyl-CoA thioesters to give a trans 2,3-unsaturated product by removal of the two pro-R hydrogen atoms.
  • The enzyme from beef liver accepts substrates with acyl chain lengths of 3 to 8 carbon atoms.
  • The highest activity was reported with either butanoyl-CoA or pentanoyl-CoA.
  • The enzyme from rat has only 10% activity with hexanoyl-CoA (compared to butanoyl-CoA) and no activity with octanoyl-CoA.
  • Cf. EC 1.3.8.7, EC 1.3.8.8 and EC 1.3.8.9.
  • Formerly EC 1.3.2.1 and EC 1.3.99.2.
