Metabolite Identification
Common NamePromysalin
DescriptionPromysalin is a secondary metabolite classified as an amphipathic antibiotic, isolated from Pseudomonas putida and Pseudomonas promysalinigenes. Its chemical structure is characterized by a unique combination of salicylic acid, proline, and myristic acid, which are assembled through a proposed hybrid non-ribosomal peptide synthetase-polyketide synthase (NRPS-PKS) biosynthetic pathway (PMID:37567320 ). Promysalin exhibits potent species-specific inhibition of the pathogen Pseudomonas, primarily through the inactivation of succinate dehydrogenase, a critical enzyme in the tricarboxylic acid cycle (PMID:37567320 ). The structure-activity relationship studies have revealed a novel binding site for promysalin on succinate dehydrogenase, which facilitates π-π stacking interactions with a nearby tryptophan residue, suggesting a mechanism for its inhibitory action (PMID:40126084 ). Additionally, promysalin has been shown to work synergistically with vancomycin and antagonistically with aminoglycosides, indicating its potential utility in combination therapies, although these interactions do not reduce minimum inhibitory concentrations (PMID:37938982 ). These findings highlight the intricate chemical interactions and biological pathways involving promysalin, underscoring its significance in antimicrobial research (PMID:40126084 ).
