CC   -!- FUNCTION: Catalyzes the irreversible beta-carboxylation of
CC       phosphoenolpyruvate (PEP) to form oxaloacetate (OAA), a four-carbon
CC       dicarboxylic acid source for the tricarboxylic acid cycle.
CC       {ECO:0000255|HAMAP-Rule:MF_01904}.
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         Evidence={ECO:0000255|HAMAP-Rule:MF_01904};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01904};
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01904}.
CC   -!- SIMILARITY: Belongs to the PEPCase type 2 family. {ECO:0000255|HAMAP-
CC       Rule:MF_01904}.
