Figure 5

Ribbon representation of the NRP-1 binding site with RPAR analogs docking in NRP-1 – RPAX complexes: (a) X= (D)R; (b) X= trans-II; (c) X= trans-IV; and (d) X= retro-Arg. The ligand and the interacting side chains of the receptor are depicted as solid lines. NRP-1 backbone is shown in purple and RPAX backbone in green. Hydrogen atoms are omitted for clarity. Specific interactions are drawn: hydrogen bonds are shown as blue discontinuous lines while salt bridges are marked by yellow discontinuous lines.
