CC   -!- FUNCTION: Catalyzes the decarboxylation of oxaloacetate into pyruvate.
CC       Seems to play a role in maintaining cellular concentrations of
CC       bicarbonate and pyruvate. {ECO:0000255|HAMAP-Rule:MF_01299}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + oxaloacetate = CO2 + pyruvate; Xref=Rhea:RHEA:15641,
CC         ChEBI:CHEBI:15361, ChEBI:CHEBI:15378, ChEBI:CHEBI:16452,
CC         ChEBI:CHEBI:16526; EC=4.1.1.112; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01299};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01299};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01299};
CC   -!- SUBUNIT: Homotetramer; dimer of dimers. {ECO:0000255|HAMAP-
CC       Rule:MF_01299}.
CC   -!- SIMILARITY: Belongs to the isocitrate lyase/PEP mutase superfamily.
CC       Oxaloacetate decarboxylase family. {ECO:0000305}.
