Abstract
Cytolysin, a two-component lanthipeptide comprising cytolysin S (CylLS″) and cytolysin L (CylLL″), is the only family member to exhibit lytic activity against mammalian cells in addition to synergistic antimicrobial activity. A subset of the thioether cross-links of CylLS″ and CylLL″ have ll stereochemistry instead of the canonical dl stereochemistry in all previously characterized lanthipeptides. The synthesis of a CylLS″ variant with dl stereochemistry is reported. Its antimicrobial activity was found to be decreased, but not its lytic activity against red blood cells. Hence, the unusual ll stereochemistry is not responsible for the lytic activity.Entities:
