Figure 4. Crystal structure of Dpo4•blunt-end X-1•ddATP
(2.05 Å). (a) Overall ternary structure. Dpo4 was shown in
grey ribbons while DNA and ddATP were shown as ball-and-stick
models. The ddATP is highlighted in magenta. The Ca^2+ ion was
shown in a green sphere. (b) The zoomed in view of the active
site including ddATP and the blunt-end base-pair. The residues
in contact with ddATP were shown as ball-and-stick models (grey
for atom C, red for atom O, yellow for atom S). Only the side
chain and main chain atoms involved were shown. (c) 2F[o] - F[c]
electron density map contoured at 1.2 σ (light-blue) of the
active site. The amino acid residues, two blunt-end DNA
base-pairs, and incoming ddATP were shown as ball-and-stick
models. Figure 4. Crystal structure of Dpo4•blunt-end
