CC   -!- FUNCTION: Na(+)/H(+) antiporter that extrudes sodium in exchange for
CC       external protons.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3 H(+)(out) + 2 Na(+)(in) = 3 H(+)(in) + 2 Na(+)(out);
CC         Xref=Rhea:RHEA:29247, ChEBI:CHEBI:15378, ChEBI:CHEBI:29101;
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:29248;
case not defined <Property:Membrane> or <Property:Membrane=1>
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
end case
CC   -!- SIMILARITY: Belongs to the NhaB Na(+)/H(+) (TC 2.A.34) antiporter
CC       family.
