β¦ Synopsis
Sumnary: Total synthesis of a lanthionine peptide nisin was successfully achieved for the first time by application of new methods for preparations of dehydroalanine and lanthionine moieties, resulting in a confirmation of the proposed structure. A peptide antibiotic nisin has been used as a food preservative, since it shows a remarkable antibacterial activity particularly against Clostridium botulinum. Nisin was first found in 1928') but isolated by Mattick et al. in 1947 ) 2 from Streptococcus lactis -. Its unique

The polycyclic peptide antibiotic, Nisin, has been analysed by plasma desorption mass spectrometry using two different sample preparation techniques and two versions of the commercial plasma desorption mass spectrometer, and a prototype with high resolving power. The spectra obtained allow identific
The peptide antibiotic nisin is shown to disrupt valinomycin-induced potassium diffusion potentials imposed on intact cells of Staphylococcus cohnii 22. Membrane depolarization occurred rapidly at high diffusion potentials while at low potentials nisin-induced depolarization was slower suggesting th
