Metabolite Identification
Common NamePantocin A
DescriptionPantocin A is a peptide-derived antibiotic belonging to the class of ribosomally synthesized and post-translationally modified peptides (RiPPs). This metabolite is produced by Pantoea species and plays a significant role in biological control, particularly against plant pathogens such as Erwinia amylovora. The biosynthesis of Pantocin A involves the enzyme PaaA, which catalyzes the transformation of glutamic acid residues into its bicyclic core structure (PMID:32109054 ). Studies indicate that Pantocin A exhibits a broad spectrum of antimicrobial activity, with its production linked to other metabolites like PNP-3, suggesting a complex interplay in the inhibition of various pathogens (PMID:32062363 ). Notably, the presence of Pantocin A has been confirmed through LC-MS/MS profiling, highlighting its significance among other bioactive compounds produced by different bacterial genera (PMID:40614942 ). Furthermore, research has demonstrated that mutants deficient in PNP-2 can still inhibit Erwinia amylovora, underscoring the importance of Pantocin A as a secondary antibiotic (PMID:32416447 ). Overall, Pantocin A represents a critical component of the antimicrobial arsenal of Pantoea, contributing to its ecological role in plant health.
