  • ENGINEERING THE PRODUCTION OF A CONFORMATIONAL VARIANT OF OCCIDIOFUNGIN THAT HAS ENHANCED INHIBITORY ACTIVITY AGAINST FUNGAL SPECIES
    Publication number: 20220007652
    Abstract: Occidiofungin is a cyclic nonribosomally synthesized antifungal peptide with submicromolar activity. This invention is directed to compositions enriched for particular occidiofungin diastereomers/conformers, methods of making compositions enriched for particular diastereomers/conformers and microorganisms suitable for producing enriched compositions of particular diastereomers/conformers. Methods of treating fungal infections or plants infected by fungi are also provided.
