butanoyl-CoA:(acceptor) 2,3-oxidoreductase;
CCR
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
butanoyl-CoA:NADP+ 2,3-oxidoreductase
Reaction(IUBMB)
butanoyl-CoA + NADP+ = (E)-but-2-enoyl-CoA + NADPH + H+ [RN:R09738]
Reaction(KEGG)
Substrate
butanoyl-CoA [CPD:C00136];
NADP+ [CPD:C00006]
Product
(E)-but-2-enoyl-CoA;
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
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.
