CC -!- FUNCTION: Pore-forming subunit of a potassium efflux system that
CC confers protection against electrophiles. Catalyzes K(+)/H(+) antiport.
CC {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 (CPA2)
CC transporter (TC 2.A.37) family. KefC subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01413}.
