Figure 8 Recognition of the C20 opposite the Pr site by R109. Stereo view showing the intercalation of the Fpg triad by the minor groove and the pseudo-Watson−Crick interactions between R109 and C20. Hydrogen bonds are indicated by dashed lines. The atomic coordinates of the triad (M70/R99/F101) from the free TtFpg have been superposed and are represented by green ball-and-sticks. The figure was generated by Molscript (Kraulis et al., 1991) and Raster3-D (Merritt and Murphy, 1994).
