Figure 8.
Fig. 8. Comparison of free and bound intermediate A/B DNA
structures. Average roll (°) versus average slide (Å)
are plotted per duplex for free (red triangles) and bound (red
diamonds) Zif268 binding sites, and free (cyan triangles) and
bound (cyan diamond) binding sites for Runt. Two clusters formed
by the Zif268 and runt binding site structures are indicated
with ovals. For reference, average roll versus average slide are
plotted for the TGGG-containing A/B intermediate (green
triangle, PDB ID 1dc0),^38 and A/B intermediate structures of
d-(GGCGCC) derivatives^34 (gray dots, PDB ids 1ih2, 1ih3, 1ih4,
1ih5, 1ih6).
