CC -!- FUNCTION: Part of the ABC transporter complex CntABCDF (Opp1) involved
CC in the uptake of metal in complex with the metallophore staphylopine
CC (StP). Involved in the import of divalent metals ions such as nickel,
CC cobalt and zinc. Probably responsible for the translocation of the
CC substrate across the membrane (PubMed:23279021, PubMed:29581261). Plays
CC a major role in nickel/cobalt import in zinc-depleted conditions.
CC Contributes to virulence. Required for full urease activity in vitro
CC (PubMed:23279021). {ECO:0000269|PubMed:23279021,
CC ECO:0000269|PubMed:29581261}.
CC -!- ACTIVITY REGULATION: Nickel/cobalt import is reduced in the presence of
CC zinc. {ECO:0000269|PubMed:23279021}.
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (CntD and
CC CntF), two transmembrane proteins (CntB and CntC) and a solute-binding
CC protein (CntA). {ECO:0000305|PubMed:23279021,
CC ECO:0000305|PubMed:29581261}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000255}.
CC -!- INDUCTION: Repressed by zinc. {ECO:0000269|PubMed:23279021}.
CC -!- DISRUPTION PHENOTYPE: Deletion of the cntABCDF genes decreases nickel
CC and cobalt intracellular levels and decreases virulence.
CC {ECO:0000269|PubMed:23279021}.
CC -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC permease family. {ECO:0000305}.
