CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P69937}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P69937}.
CC   -!- SIMILARITY: Belongs to the drug/metabolite transporter (DMT)
CC       superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family.
CC       Gdx/SugE subfamily. {ECO:0000305}.
