IntEnz Enzyme Nomenclature


Accepted name:
2-methyl-branched-chain-enoyl-CoA reductase
Systematic name:
2-methyl-branched-chain-acyl-CoA:electron-transfer flavoprotein 2-oxidoreductase




A flavoprotein (FAD) from Ascaris suum. The enzyme functions in shuttling reducing power from the electron-transport chain to 2-methyl branched-chain enoyl CoA.
