Figure 7 Model of Fe2+ association with the AGGG duplex. Molecular modeling was carried out on InsightII using the Discover module. T17 is shown in yellow, G8-G10 are in pink and A7 is in green. The sodium atoms used to neutralize the phosphate backbone during minimization are not displayed for clarity. The Fe2+ atom is placed between G8 and G9 N7 moieties and is shown in orange.
