| Kills a number of Gram-positive bacteria. Acts at the level of cell wall biosynthesis by interfering with bacterial peptidoglycan biosynthesis. Specifically inhibits the conversion of the lipid II intermediate into polymeric nascent glycan strands by transglycosylation. Maturation of lantibiotics involves the enzymic conversion of Thr, and Ser into dehydrated AA and the formation of thioether bonds with cysteine. The carboxy-terminal beta-methyllanthionine undergoes decarboxylation. This is followed by membrane translocation and cleavage of the modified precursor. |
