CC -!- FUNCTION: Sodium pump that utilizes the energy of pyrophosphate
CC hydrolysis as the driving force for Na(+) movement across the membrane.
CC {ECO:0000255|HAMAP-Rule:MF_01129}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + H2O + Na(+)(in) = H(+) + Na(+)(out) + 2
CC phosphate; Xref=Rhea:RHEA:57884, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29101, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:43474; Evidence={ECO:0000255|HAMAP-Rule:MF_01129};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01129};
CC -!- ACTIVITY REGULATION: Requires K(+) for maximal activity.
CC {ECO:0000255|HAMAP-Rule:MF_01129}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01129}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01129}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01129}.
CC -!- SIMILARITY: Belongs to the H(+)-translocating pyrophosphatase (TC
CC 3.A.10) family. K(+)-stimulated subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01129}.
