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=oxaloacetate + GTP = phosphoenolpyruvate + GDP + CO2;
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}.
