abstract：:A stably-bound external binding site for ethidium cation in the major groove of B-form DNA is proposed. This complex is stabilized by hydrogen bonding between this ligand and the nucleophilic centers O6 and N7 of guanine, both of which are accessible via the major groove. This binding site is not the same as the well-...
