FIGURE 4

Stereographic views of the G8I structure. (A) Schematic view of the G8I structure (ball-and-stick) superimposed upon the native G8 structure (black ball-and-stick model). (B) Reverse orientation of the G8I structure superimposed upon the G8 native structure showing a new interaction between the 2'-OH of I8 and the imino group of A−1. This view is rotated 180o about the y-axis relative to Figure 4A. The ribose and base of G+1 have been omitted for clarity.
