IUBMB Enzyme Nomenclature


Accepted name: glutaryl-CoA dehydrogenase (non-decarboxylating)

Reaction: glutaryl-CoA + acceptor = (E)-glutaconyl-CoA + reduced acceptor

Glossary: (E)-glutaconyl-CoA = (2E)-4-carboxybut-2-enoyl-CoA

Other name(s): GDHDes; nondecarboxylating glutaryl-coenzyme A dehydrogenase; nondecarboxylating glutaconyl-coenzyme A-forming GDH

Systematic name: glutaryl-CoA:acceptor 2,3-oxidoreductase (non-decarboxylating)

Comments: The enzyme contains FAD. The anaerobic, sulfate-reducing bacterium Desulfococcus multivorans contains two glutaryl-CoA dehydrogenases: a decarboxylating enzyme (EC, and a nondecarboxylating enzyme (this entry). The two enzymes cause different structural changes around the glutaconyl carboxylate group, primarily due to the presence of either a tyrosine or a valine residue, respectively, at the active site.
