CC -!- FUNCTION: Involved in the gluconeogenesis, in growth on fatty acids and
CC is important for initiation of infection in the macrophages. Catalyzes
CC the GTP-dependent 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:0000269|PubMed:12855734}.
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 -!- INDUCTION: Up-regulated by acetate or palmitate but down-regulated by
CC glucose. {ECO:0000269|PubMed:12855734}.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene show a reduction in the
CC capacity to infect and survive in macrophages. Moreover, mice infected
CC with this mutant are able to reduce the bacterial load much more
CC effectively than mice infected with the parental wild-type bacteria.
CC {ECO:0000269|PubMed:12855734}.
CC -!- SIMILARITY: Belongs to the phosphoenolpyruvate carboxykinase [GTP]
CC family. {ECO:0000255|HAMAP-Rule:MF_00452}.
