Figure 1.
Fig. 1. Stereo diagram of the interactions between the
side chain of Arg-660 and the incoming base. In the protein,
only the O helix is represented and is colored in red, gold,
dark blue, and dark green for the ddCTP-, ddATP-, ddTTP-, and
ddGTP-trapped complexes, respectively. In the DNA, only the
dCMP/ddGTP pair is represented and is colored in green. H-bond
interactions between Arg-660 and the O6 and N7 atoms in the base
of the ddGTP are indicated by lines. Distances between atoms
involved in H-bonds are indicated.
