TGG fragments of models for the duplex TGGT cross-linked with Pt(R,R-DAB)2+ (red, left) and Pt(S,S-DAB)2+ (green, right), both superimposed with the model for the adduct with Inline graphic (blue). Structures were averaged over the production period of the MD simulations and subsequently energy-minimized using 1000 cycles of the conjugate-gradient minimizer of AMBER6.0. The structures were least-squares fitted using the Pt-G*pG* residue, which is nearly invariant in all three adducts. The arrows indicate how the two Pt(DAB)2+ adducts avoid the methyl-methyl clash.
