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 CC complex NikMNQO involved in nickel import. The complex confers CC nickel uptake upon expression in E.coli; can also transport cobalt CC with a very low affinity. Presumably responsible for energy CC coupling to the transport system. CC -!- SUBUNIT: Forms an energy-coupling factor (ECF) transporter complex CC composed of an ATP-binding protein (A component, NikO), a CC transmembrane protein (T component, NikQ) and a fused possible CC substrate-capture protein (S component, NikMN) of unknown CC stoichimetry (By similarity). CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane CC protein (By similarity). CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. CC -!- SIMILARITY: Contains 1 ABC transporter domain.
