CC   -!- FUNCTION: Involved in zinc efflux across the cytoplasmic membrane, thus
CC       reducing zinc accumulation in the cytoplasm and rendering bacteria more
CC       resistant to zinc. It may contribute to zinc homeostasis at low
CC       concentrations of zinc (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cation diffusion facilitator (CDF)
CC       transporter (TC 2.A.4) family. SLC30A subfamily. {ECO:0000305}.
