CC   -!- FUNCTION: Catalyzes the conversion of oxaloacetate (OAA) to
CC       phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic
CC       pathway that produces glucose from lactate and other precursors derived
CC       from the citric acid cycle. {ECO:0000255|HAMAP-Rule:MF_00452}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=GTP + oxaloacetate = CO2 + GDP + phosphoenolpyruvate;
CC         Xref=Rhea:RHEA:10388, ChEBI:CHEBI:16452, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:37565, ChEBI:CHEBI:58189, ChEBI:CHEBI:58702; EC=4.1.1.32;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00452};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00452};
CC       Note=Binds 1 Mn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00452};
CC   -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00452}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00452}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00452}.
CC   -!- SIMILARITY: Belongs to the phosphoenolpyruvate carboxykinase [GTP]
CC       family. {ECO:0000255|HAMAP-Rule:MF_00452}.
