Abstact

The crystal structure of the DNA minor groove biphenyl benzimidazole diamidine ligand DB819 has been determined, bound to the DNA sequence d(CGCGAATTCGCG)(2), at a resolution of 1.36 Angstrom. Conditions for reliable in silico docking that reproduce the observed position of the ligand in the minor groove have been determined.
