Insights into the Structures of DNA Damaged by Hydroxyl Radical: Crystal Structures of DNA Duplexes Containing 5-Formyluracil
Figure 5
The pair formation geometry of fU residues found in (a) fUA1, (b) fUA2, (c) fUA3, (d) fUA4, (e) fUG1, (f) fUG2, and (g) fUG3. Broken and dotted lines indicate possible hydrogen bonds and CH⋯O interactions, respectively, and values indicate atomic distances in Å. The pictures are drawn by the program RASMOL [28].
