Fig. 5. Binding geometry of peptides.

Crystal structures of all complexes of cathepsin V were superimposed. Bound peptides are shown on the background of cathepsin V active site residues shown as gray sticks and the surface is shown in semi-transparent gray. The bound peptides are shown as stick models colored according to the patterns (a) I (red), (b) II (purple), (c) III (blue) and (d) IV (violet). Chlorine ions are shown as green balls and MPD molecules as dark gray sticks. The figures were generated with MAIN⁵⁹ and rendered with RASTER 3D⁶⁶.
