CC   -!- FUNCTION: Multidrug efflux pump that acts independently of NorA and is
CC       one of the factors that confers resistance against diverse quinolones
CC       and chemical compounds. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the major facilitator superfamily. TCR/Tet
CC       family. {ECO:0000305}.
