Enzyme Information

1.3.8.6
Glutaryl-CoA dehydrogenase (ETF).
based on mapping to UniProt Q92947
Glutaryl-CoA + electron-transfer flavoprotein = crotonyl-CoA + CO(2) + reduced electron-transfer flavoprotein.
-!- The enzyme catalyzes 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 7.2.4.5). -!- 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 catalyzes the oxidation to glutaconyl-CoA (EC 1.3.99.32). -!- Formerly EC 1.3.99.7.
