- W2076615095 abstract "The interaction of chromomycin A3 with the oligodeoxyribonucleotides 1, d(ATGCAT), 2, d(ATCGAT), 3, d(TATGCATA), and 4, d(ATAGCTAT), has been investigated by 1H and 31P NMR. In the presence of Mg2+, chromomycin binds strongly to the three GC-containing oligomers 1, 3, and 4 but not to the CG-containing oligomer 2. The proton chemical shift changes for 1 and 3 are similar, and these DNA duplexes appear to bind with a stoichiometry of 2 drugs:1 Mg2+:1 duplex. The same stoichiometry of 2 drugs:1 duplex is confirmed with 4; however, proton chemical shift changes differ. An overall C2 symmetry is exhibited by the drug complex with 1, 3, and 4. At a molar ratio of 2.0 (drugs:duplex), no free DNA proton NMR signals remain. Two-dimensional nuclear Overhauser exchange spectroscopy (NOESY) of the saturated chromomycin complex with 1 and 3 positions both chromomycinone hydroxyls and the E carbohydrates in the minor groove and provides evidence suggesting that the B carbohydrates lie on the major-groove side. This is supported by several dipolar coupling cross-peaks between the drug and the DNA duplex. Drug-induced conformational changes in duplex 1 are evaluated over a range of NOESY mixing times and found to possess some characteristics of both B-DNA and A-DNA, where the minor groove is wider and shallower. A widening of the minor groove is essential for the DNA duplex to accommodate two drug molecules. This current minor-groove model is a substantial revision of our earlier major-groove model [Keniry, M.A., Brown, S.C., Berman, E., & Shafer, R.H. (1987) Biochemistry 26, 1058-1067] and is in agreement with the model recently proposed by Gao and Patel [Gao, X., & Patel, D. J. (1989a) Biochemistry 28, 751-762]." @default.
