Metabolite Identification
Common NameVulnibactin
DescriptionVulnibactin is a catecholate siderophore, a chemical class of iron-chelating compounds that facilitate the uptake of ferric ions from the environment. This metabolite is produced by the pathogenic bacterium Vibrio vulnificus, specifically strain M2799, and plays a crucial role in iron acquisition, which is vital for bacterial virulence and survival. The biosynthesis and utilization of vulnibactin involve several key proteins, including the ferric-vulnibactin receptor protein (VuuA), the periplasmic binding protein (FatB), and the ferric-vulnibactin reductase (VuuB), which together form a sophisticated iron-utilization system (PMID:38825472 ). Additionally, the vulnibactin-export system is comprised of various components, including TolCV1 and RND proteins, which facilitate the secretion of vulnibactin into the extracellular environment (PMID:34940709 ). The ability of V. vulnificus to secrete vulnibactin underscores its pathogenic potential, as it effectively captures iron (III) ions necessary for its growth and virulence (PMID:32681432 ). Understanding the biochemical pathways and genetic regulation of vulnibactin can provide insights into the mechanisms of bacterial iron acquisition and potential therapeutic targets (PMID:40151886 ).
