Albopeptins, discovered from Streptomyces albofaciens in 1986, are effective antibiotics against plant diseases but pose challenges in determining their chemical structures due to unusual properties.
This study outlines the structural elucidation of albopeptin B, starting from a unique C13-fatty acid and constructing its octapeptide core using advanced NMR techniques.
Additionally, MS/MS data confirmed the structure of other albopeptin members and suggested a biosynthetic pathway akin to that of long-chain fatty acid lanthipeptides.
