Figure 5. Proposed mechanisms of blunt-end additions of (a)
dPTP and (b) dATP. dATP and dPTP are represented by A and P in
different colors, respectively. The Watson-Crick hydrogen bonds
were drawn as dashed lines while the base-stacking interactions
were shadowed in green. The stacking interactions between the
2′-deoxyribose (R) of an incoming nucleotide and the
5′-terminal base A are displayed in a green box. The van der
Waals interactions between an incoming nucleotide and Dpo4
active site residues were not shown for clarity. Figure 5.
