Butyryl-CoA dehydrogenase

In enzymology, a butyryl-CoA dehydrogenase (EC1.3.99.2) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are butyryl-CoA and an acceptor, whereas its two products are 2-butenoyl-CoA and reduced acceptor.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with other acceptors. The systematic name of this enzyme class is butanoyl-CoA:acceptor 2,3-oxidoreductase. Other names in common use include 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, and butanoyl-CoA:(acceptor) 2,3-oxidoreductase. This enzyme participates in 3 metabolic pathways: fatty acid metabolism, valine, leucine and isoleucine degradation, and butanoate metabolism. It employs one cofactor, FAD.
