CC   -!- FUNCTION: Catalyzes the irreversible beta-carboxylation of
CC       phosphoenolpyruvate (PEP) to form oxaloacetate (OAA), a four-
CC       carbon dicarboxylic acid source for the tricarboxylic acid cycle.
CC       {ECO:0000255|HAMAP-Rule:MF_01904, ECO:0000269|PubMed:15516590}.
CC   -!- CATALYTIC ACTIVITY: Phosphate + oxaloacetate = H(2)O +
CC       phosphoenolpyruvate + HCO(3)(-). {ECO:0000255|HAMAP-Rule:MF_01904,
CC       ECO:0000269|PubMed:15516590}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01904,
CC         ECO:0000269|PubMed:15516590};
CC       Note=Mg(2+) cannot be replaced by Mn(2+). {ECO:0000255|HAMAP-
CC       Rule:MF_01904, ECO:0000269|PubMed:15516590};
CC   -!- ENZYME REGULATION: Allosterically inhibited by L-aspartate and L-
CC       malate. PEPC activity is not affected by allosteric activators of
CC       E.coli PEPC such as glucose 6-phosphate, fructose 1,6-
CC       bisphosphate, and acetyl coenzyme A.
CC       {ECO:0000269|PubMed:15516590}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=0.09 mM for phosphoenolpyruvate
CC         {ECO:0000269|PubMed:15516590};
CC       pH dependence:
CC         Optimum pH is 8.0. {ECO:0000269|PubMed:15516590};
CC       Temperature dependence:
CC         Optimum temperature is 85 degrees Celsius.
CC         {ECO:0000269|PubMed:15516590};
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01904}.
CC   -!- SIMILARITY: Belongs to the PEPCase type 2 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01904}.
