Mode of Action: Binds to and interferes with the permeability of the cytoplasmic membrane. WebbNisin is the most prominent lantibiotic and is used as a food preservative due to its high potency against certain gram-positive bacteria (Mattick & Hirsch 1944, 1947; Rayman & Hurst 1984). It is produced by Lactococcus lactis strains belonging to serological group N.
WebbSome lantibiotics, e. g. nisin, are characterized by a dual mode of action. These peptides form a complex with the ultimate cell wall precursor lipid II, thereby inhibiting cell wall biosynthesis. The complexes then aggregate, incorporate further peptides and form a pore in the bacterial membrane.
