Figure 4: Comparison of the nucleosomal AP DNA structures with the undamaged nucleosomal DNA structure.
From: Polymorphism of apyrimidinic DNA structures in the nucleosome
Superimposition of the AP site 1 (a) and AP site 2 (b) structures of the double AP nucleosome with the corresponding regions of the undamaged nucleosome (PDB ID: 3AFA)19. The DNA strands containing the THF site are colored pink, and the THF moieties are colored red. Undamaged DNA strands are colored gray. Right panels show close-up views of the neighboring bases at the AP site 1 and the AP site 2 with the undamaged DNA in the nucleosomes.
