Part of the ABC transporter complex CntABCDF (Opp1) involved in the uptake of metal in complex with the metallophore staphylopine (StP). Involved in the import of divalent metals ions such as nickel, cobalt and zinc. Probably responsible for energy coupling to the transport system (PubMed:23279021, PubMed:29581261). Plays a major role in nickel/cobalt import in zinc-depleted conditions. Contributes to virulence. Required for full urease activity in vitro (PubMed:23279021). Nickel/cobalt import is reduced in the presence of zinc. The complex is composed of two ATP-binding proteins (CntD and CntF), two transmembrane proteins (CntB and CntC) and a solute-binding protein (CntA). Repressed by zinc. Deletion of the cntABCDF genes decreases nickel and cobalt intracellular levels and decreases virulence. Belongs to the ABC transporter superfamily.
