Crystal structure of h-Telo DNA repeat d[AG3(T2AG3)3] in the presence of K+ ions. The conformation of loop residues dT11, dT12 and dA13 in the absence (A) and presence (B) of a ligand (tetrasubstituted naphthalene diimide derivative) is shown (11,23). The PDB accession numbers are 1KF1 and 4DA3, respectively. We envisaged that pyrimidine loop residues would be potential sites for introducing conformation-sensitive probes.
