Figure 6. Comparison of surface charges in D. Tok Pol and
RB69 Pol. Accessible-surface representation of (a) D. Tok Pol
and (b) RB69 Pol in the same orientation after superposition of
their palm subdomains. Surface regions corresponding to the
terminal oxygen atoms of aspartate and glutamate are colored
red, whereas surface regions contributed by the sidechain
nitrogen of lysines and arginines are colored blue. D. Tok Pol
has a striking pairing of oppositely charged residues not seen
in RB69 pol. A representation of D. Tok Pol as a worm is
included for orientation.
