Protein

Phosphoenolpyruvate carboxykinase [ATP]

Gene

pckA

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA.3 PublicationsUniRule annotation

Catalytic activityi

ATP + oxaloacetate = ADP + phosphoenolpyruvate + CO2.1 PublicationUniRule annotation

Cofactori

Binds 1 manganese ion per subunit.5 PublicationsUniRule annotation

Enzyme regulationi

Allosterically activated by calcium. It may represent the only case of a monomeric, allosteric enzyme.4 Publications
