CC   -!- FUNCTION: Involved in the gluconeogenesis. Catalyzes the conversion of
CC       oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct
CC       phosphoryl transfer between the nucleoside triphosphate and OAA.
CC       {ECO:0000255|HAMAP-Rule:MF_00453}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + oxaloacetate = ADP + CO2 + phosphoenolpyruvate;
CC         Xref=Rhea:RHEA:18617, ChEBI:CHEBI:16452, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:58702, ChEBI:CHEBI:456216;
CC         EC=4.1.1.49; Evidence={ECO:0000255|HAMAP-Rule:MF_00453};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00453};
CC       Note=Binds 1 Mn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00453};
CC   -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00453}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00453}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00453}.
CC   -!- SIMILARITY: Belongs to the phosphoenolpyruvate carboxykinase (ATP)
CC       family. {ECO:0000255|HAMAP-Rule:MF_00453}.
