Common NameStaphyloferrin B
DescriptionStaphyloferrin B is a siderophore, a type of small molecule that plays a critical role in iron acquisition for bacteria. Specifically produced by Staphylococcus aureus, particularly by its more invasive, coagulase-positive strains, staphyloferrin B functions to scavenge trivalent iron (Fe3+) from the environment, which is essential for bacterial growth and virulence (PMID:40173255 ). Additionally, the soil-borne phytopathogenic bacterium Ralstonia solanacearum species complex also synthesizes staphyloferrin B, indicating its significance across different bacterial species (PMID:38805410 ). The biosynthesis of staphyloferrin B involves several enzymes, including SbnE, which is essential for its production (PMID:37478559 ). Genetic studies have revealed the presence of an eight-gene cluster responsible for staphyloferrin B-like siderophore synthesis, highlighting the genetic basis of iron acquisition in these organisms (PMID:35875576 ). Furthermore, structural analyses using homology modeling have provided insights into the 3D structure of staphyloferrin B biosynthetic enzymes, enhancing our understanding of its biochemical properties (PMID:37995054 ). Despite the presence of staphyloferrin B, some mutants retain virulence, suggesting a complex relationship between different siderophores and pathogenicity (PMID:38805410 ).
