CC   -!- FUNCTION: Part of the ABC transporter complex NikABCDE (Opp2) involved
CC       in nickel import. Probably responsible for the translocation of the
CC       substrate across the membrane. {ECO:0000250|UniProtKB:Q2FYQ5}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (NikD and
CC       NikE), two transmembrane proteins (NikB and NikC) and a solute-binding
CC       protein (NikA). {ECO:0000250|UniProtKB:Q2FYQ5}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. OppBC subfamily. {ECO:0000305}.
