Figure 7 A schematic diagram showing the complicated hydration
structure in the minor groove between the Gua4-Cyt9 and
Gua6-Cyt7 base pairs. The three D[2]O molecules with underlined
labels (D[2]O121, D[2]O137 and D[2]O113) are located at the
bottom of the minor groove. This diagram includes all covalent
bonds within a radius of 7 Å from the O atom of D[2]O137.
Yellow broken lines show hydrogen bonds.
