Figure 5. Distribution of waters interacting with N3, N2, and C8 groups of the G bases. (a) All 16 G-G base-pairs are superimposed and shown as a generalized G-G pair. The number of observations for each hydration site is indicated. (b) The N2-water-O4' bridge and the C8-water-OP bridge are shown for the anti-anti G-G configuration. (c) The N2-water-OP bridge and (d) the C8-water-O4' bridge are other examples of bidentate water interactions and each of these bridges involves a base in the syn conformation.
