EC 4.1.1.32

Accepted name: phosphoenolpyruvate carboxykinase (GTP)

Reaction: GTP + oxaloacetate = GDP + phosphoenolpyruvate + CO2

Other name(s): phosphoenolpyruvate carboxylase; phosphopyruvate carboxylase; phosphopyruvate (guanosine triphosphate) carboxykinase; phosphoenolpyruvic carboxykinase (GTP); phosphopyruvate carboxylase (GTP); phosphoenolpyruvic carboxylase (GTP); phosphoenolpyruvic carboxykinase; phosphoenolpyruvate carboxykinase; PEP carboxylase; GTP:oxaloacetate carboxy-lyase (transphosphorylating)

Systematic name: GTP:oxaloacetate carboxy-lyase (adding GTP; phosphoenolpyruvate-forming)

Comments: ITP can act as phosphate donor.
