CC -!- FUNCTION: K(+)/H(+) antiporter that extrudes potassium in exchange for
CC external protons and maintains the internal concentration of potassium
CC under toxic levels. {ECO:0000255|HAMAP-Rule:MF_01075}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+)(out) + K(+)(in) = H(+)(in) + K(+)(out);
CC Xref=Rhea:RHEA:29467, ChEBI:CHEBI:15378, ChEBI:CHEBI:29103;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01075};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:29468;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01075};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01075}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01075}.
CC -!- SIMILARITY: Belongs to the monovalent cation:proton antiporter 1 (CPA1)
CC transporter (TC 2.A.36) family. NhaP2 subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01075}.
