Genetic and molecular characterization of essential components of the Vibrio anguillarum plasmid-mediated iron-transport system.

The iron-transport genes from the pJM1 plasmid of Vibrio anguillarum have been cloned and sequenced. Five open-reading frames have been identified, one of which encodes the outer membrane receptor for ferric anguibactin, OM2. This coding region corresponds to a protein of 726 amino acids with a Mr of 78,777. The protein has a hydrophobic signal sequence of 35 amino acids and a potential membrane-associated hydrophobic region at the carboxyl terminus. A 2.3-kilobase iron-regulated mRNA was transcribed from this region in vivo. The four other open-reading frames were shown to be involved in the regulation of OM2 expression and in iron transport by the use of insertion mutagenesis and complementation analysis. One of these open-reading frames, ORF3, encodes a 40-kDa polypeptide which, as deduced from the amino acid sequence and the hydropathy plot, is likely to be membrane-associated and together with OM2 may play a role in the transport of iron into the cell cytosol.[1]
