    • Similar high sensitivities to nisin are found for other Gram-positive bacteria. For instance, Lactococcus lactis and Streptococcus thermophilus have MIC values of 4.5 nM and 1.8 nM, respectively.

    • The observation that vancomycin inhibits nisin activity in vivo suggests that vancomycin and nisin bind to the same site at Lipid II. However, enterococci expressing the vanA-type resistance gene cluster showed high vancomycin resistance relative to an isogenic strain not expressing the gene cluster (by a factor of >250), whereas the vancomycin-resistant strain remained as sensitive to nisin as the nonresistant strain (I. Wiedemann and H.-G. Sahl, data not shown). Thus, vancomycin and nisin do not share the same binding site on Lipid II.

    • For instance, about 45% leakage could be observed for intact M. flavus cells with 10 nM nisin (Fig. 2), whereas about 20% leakage could be observed for the isolated membranes with 30 nM nisin (Fig. 3A).

    • -1. This was determined as described (17) using vesicles composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine containing 0.5 mol % Lipid II. Under the assumption that only the Lipid II molecules on the outside of the vesides were available for binding, nisin bound to Lipid II with a 2:1 stoichiometry. However, if nisin can translocate across the lipid bilayer in the presence of Lipid II, as was reported for pure phospholipid systems (4), then the stoichiometry would become 1:1.
