Figure 8

(a) Radial distribution functions (RDFs) between central carbon atoms in different Arg9 peptides in the 12 peptides/128 lipids Arg9–POPC+POPG system. The RDFs marked by arrows denote direct contact pairs between central carbon atoms in guanidinium moieties present in long-living Arg9–Arg9 aggregates. (b) Same plot as panel a for the central nitrogen atoms on different Lys9 peptides. Snapshots of (c) top-down view and (d) side-on view of two individual peptides (depicted in the blue and red stick drawings) is shown forming an aggregate in the 12 peptides/128 lipids Arg9–POPC+POPG system. The guanidinium groups in close contact are shown with a van der Waals representation.
