Description
Mode of action:
Lanthionine-containing peptide antibiotic (lantibiotic). The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores.
Post-translational modification:
Maturation of lantibiotics involves the enzymic conversion of Thr, and Ser into dehydrated AA and the formation of thioether bonds with cysteine. This is followed by membrane translocation and cleavage of the modified precursor.
Producer strain:
Staphylococcus simulans produces Nukacin 3299 (formerly designated simulancin 3299), a bacteriocin that is identical to nukacin ISK-1 [view ref].
