CC   -!- FUNCTION: Regulatory subunit of a potassium efflux system that
CC       confers protection against electrophiles. Required for full
CC       activity of KefC. Shows redox enzymatic activity, but this
CC       enzymatic activity is not required for activation of KefC.
CC       {ECO:0000255|HAMAP-Rule:MF_01414}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a quinone + H(+) + NADH = a quinol + NAD(+);

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01414};
CC   -!- SUBUNIT: Homodimer. Interacts with KefC. {ECO:0000255|HAMAP-
CC       Rule:MF_01414}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01414}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01414}; Cytoplasmic side {ECO:0000255|HAMAP-
CC       Rule:MF_01414}.
CC   -!- SIMILARITY: Belongs to the NAD(P)H dehydrogenase (quinone) family.
CC       KefF subfamily. {ECO:0000255|HAMAP-Rule:MF_01414}.
