Comments [?]

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 RHEA:18617: ATP + oxaloacetate = ADP + CO2 + phosphoenolpyruvate
EC 4.1.1.49
Cofactor Mn(2+)
Note: Binds 1 Mn(2+) ion per subunit.
Pathway Carbohydrate biosynthesis; gluconeogenesis.
case <OC:Gammaproteobacteria>
Subunit Monomer.
end case
Subcellular location Cytoplasm.
Similarity Belongs to the phosphoenolpyruvate carboxykinase (ATP) family.
