CC   -!- FUNCTION: Catalyzes the decarboxylation of oxaloacetate coupled to
CC       Na(+) translocation. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + 2 Na(+)(in) + oxaloacetate = CO2 + 2 Na(+)(out) +
CC         pyruvate; Xref=Rhea:RHEA:57724, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:16452, ChEBI:CHEBI:16526, ChEBI:CHEBI:29101; EC=7.2.4.2;
CC   -!- COFACTOR:
CC       Name=Na(+); Xref=ChEBI:CHEBI:29101; Evidence={ECO:0000250};
CC   -!- SUBUNIT: Heterotrimer of an alpha, a beta and a gamma subunit.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the OadG family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAF93958.1; Type=Erroneous initiation; Evidence={ECO:0000305};
