    • MOA

    • The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores.
    • PTM

    • Maturation of lantibiotics involves the enzymic conversion of Thr, and Ser into dehydrated AA and the formation of thioether bonds with cysteine. The 62-67 beta-methyllanthionine thioether bond is oxidized to a sulfoxide. This is followed by membrane translocation and cleavage of the modified precursor
