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. Webb16 okt. 2024 · MECHANISM OF ANTIMICROBIAL ACTION OF NISIN For its killing activity, nisin does not require a membrane receptor on its target cell. This is unlike killing activity of many bacteriocins such as colicin that need membrane receptors on target cells. There are two major steps for nisin to kill sensitive cells. 1. Passage through cell wall
