FIG. 5.

Binding mode of PS–DNA aptamer, SIAp4. The surface representations of SIAp4 at 20 ns in the simulation using initial structure marked by blue in the inset of Fig. 3 are presented. PS is plotted in the CPK (ball-and-stick) format. Red color represents negative, blue for positive, and white for neutral charge. The scale of color denotes the magnitude of charge. The plot was generated using VMD (Humphrey et al., 2006).
