TypeSYSTEM
DescriptionA nine-gene operon, sbn, encodes genes for staphylobactin biosynthesis and export. This siderophore, or ferric iron (Fe3+) chelator, contributes to survival, and therefore virulence, by Staphylococcus aureus in host tissues. Its reported size by m/z is 822, larger than staphyloferrins A (480) or B (448). SbnD appears to be the efflux transporter, SbnI is not homologous to known enzymes, and the other seven all appear by homology to be enzymes. Mutation of SbnE leads to a defect in staphylobactin biosynthesis, and an adjacent ABC transporter system, not currently part of this genome property, takes up ferric staphylobactin. Note that staphylobactin may be closely to staphyloferrin B, as all proteins but sbnI have close homologs in Ralstonia solanacearum GMI1000, which is phylogenetically extremely distant. R. solanacearum, however, makes staphyloferrin B like most strains of Staphylococcus aureus. S. aureus RN6390, meanwhile, appears to makes staphylobactin in place of staphyloferrin B.
