The results suggest that when active nisin is accumulated in the cytoplasm, it can insert into the membrane and from there extrude... WebThe antimicrobial peptide, nisin, produced by several strains of Lactococcus lactis, which belongs to the Class I bacteriocins called lantibiotics, is a small (3.4 kDa), 34-amino acid, cationic, hydrophobic peptide and has the five characteristic (β-methyl)lanthionine rings formed by significant post-translational modification.
