IUBMB Enzyme Nomenclature


Accepted name: succinate—CoA ligase (GDP-forming)

Reaction: GTP + succinate + CoA = GDP + phosphate + succinyl-CoA

Other name(s): succinyl-CoA synthetase (GDP-forming)

Other name(s): succinyl-CoA synthetase (GDP-forming); succinyl coenzyme A synthetase (guanosine diphosphate-forming); succinate thiokinase (ambiguous); succinic thiokinase (ambiguous); succinyl coenzyme A synthetase (ambiguous); succinate-phosphorylating enzyme (ambiguous); P-enzyme; SCS (ambiguous); G-STK; succinyl coenzyme A synthetase (GDP-forming); succinyl CoA synthetase (ambiguous)

Systematic name: succinate:CoA ligase (GDP-forming)

Comments: Itaconate can act instead of succinate, and ITP instead of GTP.
