Metabolite Identification
Common NameMirubactin
DescriptionMirubactin is a siderophore belonging to the chemical class of O-acyl hydroxamic acid esters. Its unique chemical structure features an unprecedented functionality among natural products, which facilitates its role in iron acquisition. Mirubactin is produced by the actinobacterium Actinosynnema mirum, and its biosynthetic gene cluster has been identified, indicating a complex pathway for its synthesis (PMID:22578145 ). The compound has been shown to rescue the lethal effects of cell wall biosynthesis mutations in Bacillus subtilis, suggesting its involvement in bacterial growth and survival under stress conditions (PMID:36312962 ). Notably, mirubactin C, a derivative of mirubactin A, has demonstrated growth-rescuing activity in low micromolar concentrations, although this effect is not solely attributed to iron sequestration, indicating additional biological mechanisms at play (PMID:36312962 ). Furthermore, mirubactin can degrade into multiple siderophores with varying Fe(III) chelation properties, enhancing its functional versatility in iron acquisition (PMID:35703354 ). Overall, mirubactin exemplifies the intricate interplay between microbial metabolites and their ecological roles, particularly in iron homeostasis.
