Serratamolide purification and verification of biological activity. A.
Structure of serratamolide. B. HPLC trace of spent supernatants from a swrW mutant with either an empty vector (swrW+vector) or a swrW expression plasmid (swrW+pswrW). The expected peak for serratamolide is indicated by an arrow. C. Swarming motility of an swrW mutant treated with DMSO or purified serratamolide. This shows that the purified compound restores swarming motility as expected.
