FatB domain (IPR033870)

Short name: FatB

Overlapping homologous superfamilies


Domain relationships


Proteins with this domain are periplasmic binding proteins involved in siderophore-mediated iron uptake in some eubacterial species, such as FatB in Vibrio anguillarum [PMID: 7476205, PMID: 1748657] and CeuE in Campylobacter coli [PMID: 8574410]. FatB is encoded in Vibrio anguillarum plasmid pJM1, which harbours the genes for the biosynthesis of the siderophore anguibactin and the ferric anguibactin transport proteins FatD, C, B and A [PMID: 3013839, PMID: 12460538]. FatB is a periplasmic lipoprotein and may not be essential for ferric anguibactin transport [PMID: 21304833] as Vibrio anguillarum plasmid pJM1 seems to carry two ABC transporter systems participating in siderophore transport [PMID: 23350649].
