Hydrogen bonding interaction between Arg-332 and the oxygen atom at the C8 position of 8-oxodG was observed in an 8-oxodG:dCTP pair but not in a 8-oxodG:dATP pair in the Dpo4 active site. The protein is shown with schematic helices and strands. The DNA duplex and selected Dpo4 residues are shown in a stick mode. Ca2+ ions and water molecules are shown as yellow and red spheres, respectively, and hydrogen bonds as dashed lines. These figures are cited from Eoff et al., J. Biol. Chem. 282 (2007) 19831-19843 [55].
