IntEnz Enzyme Nomenclature


Accepted name:
glutaryl-CoA dehydrogenase (ETF)
Other names:
glutaryl coenzyme A dehydrogenase
glutaryl-CoA:(acceptor) 2,3-oxidoreductase (decarboxylating)
glutaryl-CoA dehydrogenase
Systematic name:
glutaryl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase (decarboxylating)




Contains FAD. The enzyme catalyses the oxidation of glutaryl-CoA to glutaconyl-CoA (which remains bound to the enzyme), and the decarboxylation of the latter to crotonyl-CoA (cf. EC, glutaconyl-CoA decarboxylase). FAD is the electron acceptor in the oxidation of the substrate, and its reoxidation by electron-transfer flavoprotein completes the catalytic cycle. The anaerobic, sulfate-reducing bacterium Desulfococcus multivorans contains two glutaryl-CoA dehydrogenases: a decarboxylating enzyme (this entry), and a non-decarboxylating enzyme that only catalyses the oxidation to glutaconyl-CoA (EC
