Figure 3. Hydrogen-Bonding Networks
(A) Hydrogen bonding
between the dGTP base and polymerase in the Polι[Abasic.dGTP]
ternary complex. The relevant DNA and protein residues are
colored according to element, the water molecules are shown as
red spheres, and the hydrogen bonds are displayed as dashed
lines.
(B) Hydrogen bonding between the dTTP base and
polymerase in the Polι[Abasic.dTTP] ternary complex.
(C)
Hydrogen bonding between the dATP base and polymerase in the
Polι[Abasic.dATP] ternary complex.
