FUNCTION | Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA. |
CATALYTIC ACTIVITY | Reaction=ATP + oxaloacetate = ADP + CO2 + phosphoenolpyruvate; Xref=Rhea:RHEA:18617, ChEBI:CHEBI:16452, ChEBI:CHEBI:16526, ChEBI:CHEBI:30616, ChEBI:CHEBI:58702, ChEBI:CHEBI:456216; EC=4.1.1.49; |
COFACTOR | Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Note=Binds 1 Mn(2+) ion per subunit.; |
PATHWAY | Carbohydrate biosynthesis; gluconeogenesis. |
