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. plasmid DNA. The sequences reported are absolutely identical.

Red solid plot : values according to the hydrophobicity scale of Kyte and Doolittle (reference paper).


Yellow dashed plot : Experimentally determined hydrophobicity scale for proteins at membrane interfaces(reference paper).


Green dotted-dashed plot : prediction of transmembrane helices (reference paper). In this scale (unlike the others), more negative values reflect greater hydrophobicity.
