ENZYME entry: EC

Accepted Name
Crotonyl-CoA reductase.
Alternative Name(s)
3-hydroxyacyl CoA reductase.
Butyryl-CoA dehydrogenase.
Enoyl-coenzyme A reductase.
Ethylene reductase.
Short-chain acyl-coenzyme A dehydrogenase.
Unsaturated acyl coenzyme A reductase.
Reaction catalysed
Butanoyl-CoA + NADP(+) <=> (E)-but-2-enoyl-CoA + NADPH
  • Catalyzes the reaction in the reverse direction.
  • This enzyme from Streptomyces collinus is specific for (E)-but-2- enoyl-CoA, and is proposed to provide butanoyl-CoA as a starter unit for straight-chain fatty acid biosynthesis.
