Fig. 6From: Effect of central PxxP motif in amphipathic alpha-helical peptides on antimicrobial activity and mode of actionTrp fluorescence spectra and emission maxima (λmax) of the peptides. A KL18 and B KL-PxxP were added in buffer (black) and in the presence of vesicles composed of PC/PG (green), or PC (red) at a peptide/lipid molar ratio of 1:100Back to article page
