In enzymology, a 2-methyl-branched-chain-enoyl-CoA reductase (EC 1.3.8.5) is an enzyme that catalyzes the chemical reaction
- 2-methylbutanoyl-CoA + electron transfer flavoprotein [math]\displaystyle{ \rightleftharpoons }[/math] 2-methylcrotonoyl-CoA + reduced electron transfer flavoprotein + H+
Thus, the two substrates of this enzyme are 2-methylbutanoyl-CoA and an electron transfer flavoprotein, whereas its 3 products are 2-methylcrotonoyl-CoA, reduced electron transfer flavoprotein, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donors with flavin as acceptor. The systematic name of this enzyme class is 2-methyl-branched-chain-acyl-CoA:electron-transfer flavoprotein 2-oxidoreductase . This enzyme participates in the degradation of isoleucine. It employs one cofactor, FAD.
