CC   -!- FUNCTION: Pore-forming subunit of a potassium efflux system that
CC       confers protection against electrophiles. Catalyzes K(+)/H(+)
CC       antiport. {ECO:0000255|HAMAP-Rule:MF_01413}.
CC   -!- SUBUNIT: Homodimer. Interacts with the regulatory subunit KefF.
CC       {ECO:0000255|HAMAP-Rule:MF_01413}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01413}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01413}.
CC   -!- SIMILARITY: Belongs to the monovalent cation:proton antiporter 2
CC       (CPA2) transporter (TC 2.A.37) family. KefC subfamily.
