PubMed Abstract: The drug chromomycin-A(3) binds to the minor groove of DNA and requires a divalent metal ion for complex formation. (1)H, (31)P and (13)C pseudocontact shifts occurring in the presence of a tightly bound divalent cobalt ion in the complex between d(TTGGCCAA)(2) and chromomycin-A(3) have been used to determine the structure of the complex. The accuracy of the structure was verified by validation with nuclear Overhauser enhancements (NOEs) and J-coupling constants not used in the structure calculation.
