FUNCTION | Catalyzes the irreversible beta-carboxylation of phosphoenolpyruvate (PEP) to form oxaloacetate (OAA), a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. |
CATALYTIC ACTIVITY | Reaction=oxaloacetate + phosphate = hydrogencarbonate + phosphoenolpyruvate; Xref=Rhea:RHEA:28370, ChEBI:CHEBI:16452, ChEBI:CHEBI:17544, ChEBI:CHEBI:43474, ChEBI:CHEBI:58702; EC=4.1.1.31; |
COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
SUBUNIT | Homotetramer. |
SIMILARITY | Belongs to the PEPCase type 2 family. |
