CC   -!- FUNCTION: Through the carboxylation of phosphoenolpyruvate (PEP) it
CC       forms oxaloacetate, a four-carbon dicarboxylic acid source for the
CC       tricarboxylic acid cycle. {ECO:0000250|UniProtKB:Q02909}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=oxaloacetate + phosphate = hydrogencarbonate +
CC         phosphoenolpyruvate; Xref=Rhea:RHEA:28370, ChEBI:CHEBI:16452,
CC         ChEBI:CHEBI:17544, ChEBI:CHEBI:43474, ChEBI:CHEBI:58702; EC=4.1.1.31;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC   -!- ACTIVITY REGULATION: Activated by glutamine and dihydroxyacetone
CC       phosphate. Inhibited by glutamate, aspartate, 2-oxoglutarate and
CC       malate. {ECO:0000269|PubMed:9512480}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 8.1.;
CC   -!- SUBUNIT: Exists as a homotetramer or heterooligomer.
CC       {ECO:0000269|PubMed:9512480, ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PEPCase type 1 family. {ECO:0000305}.
