CC   -!- FUNCTION: Part of a cation efflux system that mediates resistance to
CC       copper and silver. Binds one copper per polypeptide (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: The cus efflux system is composed of CusA, CusB, CusC and
CC       CusF. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC   -!- INDUCTION: Transcriptionally regulated by CusR in response to copper
CC       and silver ions. {ECO:0000305}.
