CC -!- FUNCTION: Probable transporter of a GTP-driven Fe(2+) uptake system
CC across the cell inner membrane into the cytoplasm, shown for strain
CC NCTC 11168 (PubMed:16988218). {ECO:0000269|PubMed:16988218}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:P33650}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P33650}.
CC -!- INDUCTION: Detected in iron-restricted, mid-log-phase cells, part of
CC the feoA-feoB operon (strain NCTC 11168).
CC {ECO:0000269|PubMed:16988218}.
CC -!- DISRUPTION PHENOTYPE: Loss of 90% of Fe(2+) uptake into the cytoplasm,
CC reduced growth rate in iron-limited medium, strain NCTC 11168; in iron-
CC rich medium Fe(2+) uptake is not affected (PubMed:16988218). Reduced
CC survival in human and pig epithelial cells after 3 days, strain 81-176
CC (PubMed:16988218). Reduced ability to colonize chick cecum, strains 81-
CC 176, ATCC 43431 and NCTC 11168 (PubMed:16988218). Outcompeted by wild-
CC type bacteria in infection assays in piglets; the 3 different strains
CC colonize different regions of the gut differently (PubMed:16988218).
CC {ECO:0000269|PubMed:16988218}.
CC -!- MISCELLANEOUS: Fe(2+) ion uptake in diverse strains of C.jejuni is much
CC lower than in E.coli and H.pylori. Site-directed mutations in FeoB
CC cause no defect in Fe(2+) uptake.
CC -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like
CC GTPase superfamily. FeoB GTPase (TC 9.A.8) family.
CC {ECO:0000255|PROSITE-ProRule:PRU01048}.
CC -!- CAUTION: Has been reported not to be involved in Fe(2+) uptake in
CC strains F38001 and M129, when the strains were grown in iron-containing
CC medium (PubMed:14735223). When the feoB deletion strain of NCTC 11168
CC is grown in iron-containing medium Fe(2+) uptake occurs, suggesting the
CC prior results in strain F38001 and M129 may not be correct
CC (PubMed:16988218). {ECO:0000269|PubMed:14735223,
CC ECO:0000269|PubMed:16988218}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAR20450.1; Type=Erroneous termination; Note=Truncated C-terminus. Strain F38011 sequence differs due to a recombination event that leads to a 68-bp deletion producing a stop codon at position 544.; Evidence={ECO:0000305};
