Antimicrobial Peptides: Their Role as Infection-Selective Tracers for Molecular Imaging

Figure 3

Statistical analysis of residue distribution in the 20-residue N-terminal stretch α-helical AMPs from natural sources. A graphical representation of the frequency of different types of residue at each position on a helical wheel projection is shown. The uneven distribution of hydrophobic and charged peptides contributes to the amphipathic nature of the peptide (adapted from Tossi et al. [17]).
