Fig. 10. Structures of the 3,N4-εdC adduct (X6) opposite dT, dA, and dG in the 5′-C5X6C7-3′ sequence.

Fig. 10

a) The 3,N4-εdC (syn)·T (anti) base pair. The etheno moiety is in the major groove. b) The 3,N4-εdC (anti)· A (anti) base pair, showing partial intercalation within the 3,N4-εdC (anti)·A (anti) alignment. c) The 3,N4-εdC (anti)·G (anti) base pair. The 3,N4-εdC and complementary base are shown in green and red, respectively. These illustrations were prepared from PDB entries 1B5K and 1B6Y using PyMol [39] software.
