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; succinic thiokinase; succinyl coenzyme A synthetase; succinate-phosphorylating enzyme; P-enzyme; SCS; G-STK; succinyl coenzyme A synthetase (GDP-forming); succinyl CoA synthetase; succinyl coenzyme A synthetase
Systematic name: succinate:CoA ligase (GDP-forming)
Comments: Itaconate can act instead of succinate, and ITP instead of GTP.
