Figure 2 Protein/DNA contacts in polymerizing and editing
conformations. (A) Polymerase mode. Hydrogen bond contacts less
than 2.8 Å are represented by solid lines and those greater than
2.8 and less than 3.5 Å are shown with dashed lines. Residues in
parentheses represent charge interactions longer than 3.5 Å.
Wavy lines represent water-mediated contacts. Hydrophobic
interactions are symbolized by dashed arcs. Contacts mediated by
a nitrogen main-chain atom are indicated by the suffix 'N'.
Protein residues are colored according to their domain location:
exonuclease (cyan), N-terminal domain (orange), palm (red),
thumb (green) and fingers (blue). Underlined residues are
contacts in Pol1 that are absent in Pol2. (B) Exonuclease mode.
All descriptions as above.
