Fig. 6From: Binding of undamaged double stranded DNA to vaccinia virus uracil-DNA GlycosylaseProtein-DNA interactions at the Leu-intercalation loop. Cartoon and stick drawing displaying hydrogen bonding interactions at the Leu-intercalation loop region between the D4 residues in A and B subunits with partner DNA strands. Relevant D4 residues are shown in stick models and are labeled. DNA chains are shown as lines. Hydrogen bonding distances shown are in Å. Residues 184–188 were missing from both subunitsBack to article page
