EC 1.3.1.86

Accepted name: crotonyl-CoA reductase

Reaction: butanoyl-CoA + NADP+ = (E)-but-2-enoyl-CoA + NADPH + H+

Glossary: (E)-but-2-enoyl-CoA = crotonyl-CoA, butanoyl-CoA = butyryl-CoA

Other name(s): butyryl-CoA dehydrogenase; butyryl dehydrogenase; unsaturated acyl-CoA reductase; ethylene reductase; enoyl-coenzyme A reductase; unsaturated acyl coenzyme A reductase; butyryl coenzyme A dehydrogenase; short-chain acyl CoA dehydrogenase; short-chain acyl-coenzyme A dehydrogenase; 3-hydroxyacyl CoA reductase; butanoyl-CoA:(acceptor) 2,3-oxidoreductase; CCR

Systematic name: butanoyl-CoA:NADP+ 2,3-oxidoreductase

Comments: Catalyses 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.
