RC STRAIN=ATCC BAA-309 / NBRC 16581 / SB1003; RX PubMed=16352848; DOI=10.1128/jb.188.1.317-327.2006; RA Rodionov D.A., Hebbeln P., Gelfand M.S., Eitinger T.; RT "Comparative and functional genomic analysis of prokaryotic nickel and RT cobalt uptake transporters: evidence for a novel group of ATP-binding RT cassette transporters."; RL J. Bacteriol. 188:317-327(2006). CC -!- FUNCTION: Part of the energy-coupling factor (ECF) transporter complex CC NikMNQO involved in nickel import. The complex confers nickel uptake CC upon expression in E.coli; can also transport cobalt with a very low CC affinity. Presumably responsible for energy coupling to the transport CC system. {ECO:0000269|PubMed:16352848}. CC -!- SUBUNIT: Forms an energy-coupling factor (ECF) transporter complex CC composed of an ATP-binding protein (A component, NikO), a transmembrane CC protein (T component, NikQ) and a fused possible substrate-capture CC protein (S component, NikMN) of unknown stoichimetry. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Peripheral CC membrane protein {ECO:0000250}. CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. {ECO:0000305}.
