FIGURE 7.
Substrate specificity of NsrFP. Graphical representation of the fold of resistance exhibited by NsrFP with nisin and different nisin variants (CCCCA, CCCAA, CCCCP, nisin1-22 and nisin1-28) as well as nisin H and gallidermin. The NZ9000Cm and NZ9000NsrFP strains were used to determine the activity of all tested lantibiotics. The error bars indicate the standard error of at least three independent experiments.
