Lipid-donor-anchored genome mining uncovers dioxanopeptins, antibacterial lipopeptides with a 1,3-dioxane functionalized polyunsaturated lipid tail

Key Points

• The research aims to identify new antibacterial lipopeptides by focusing on the role of lipid donors in their structure.
• Utilized genome mining techniques to isolate lipopeptide structures.
• Analyzed the chemical composition of lipid tails in antibiotic candidates.
• Prioritized lipid donor-associated compounds during screening.
• Identified dioxanopeptins as new lipopeptide antibiotics.
• Demonstrated that lipid tail structures significantly enhance antibacterial activity.
• Showed potential for discovering novel antibiotics through lipid donor focus.
