RA Cao J., Woodhall M.R., Alvarez J., Cartron M.L., Andrews S.C.;
RT "EfeUOB (YcdNOB) is a tripartite, acid-induced and CpxAR-regulated, low-pH
RT Fe2+ transporter that is cryptic in Escherichia coli K-12 but functional in
RT E. coli O157:H7.";
RL Mol. Microbiol. 65:857-875(2007).
CC -!- SUBUNIT: Part of a ferrous iron transporter composed of EfeU, EfeO and
CC EfeB. However, this EfeUOB tripartite iron transporter is defective in
CC E.coli strain K12 due to a frameshift mutation in EfeU.
CC {ECO:0000269|PubMed:17627767}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the oxidase-dependent Fe transporter (OFeT) (TC
CC 9.A.10.1) family. {ECO:0000305}.
CC -!- CAUTION: Could be the product of a pseudogene. Strain K12 contains a
CC truncated, inactive permease due to a frameshift in position 34 that
CC produces two separate ORFs. The sequence shown here is a reconstruction
CC originating from EcoGene. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AP009048; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=U00096; Type=Frameshift; Evidence={ECO:0000305};
