Sections from NOESY spectra (τm = 250 ms, 35°C) of distamycin-DNA complexes. The NOEs between distamycin methyls (∼3.5 p.p.m.) and G4 DNA are the strongest in the NOESY spectra. NOE cross-peaks directly above * are intra-DNA; D, distamycin. (A) Distamycin-[TAGGGGGT]4 (H2O). Cross-peaks from left to right, A2 H8, DHF, A2 H2, DNH (unassigned), G3 H8, G6 H8, G7 H8, T8 H6 and T1 H6. The resonance positions of G4 H8 and G5 H8 are also indicated. (B) Distamycin-[TAGGGGTT]4 (D2O). Cross-peaks from left to right, A2 H8, DHF, G3 H8, G6 H8, T7 H6, T8 H6 and T1 H6. The resonance positions of G4 H8 and G5 H8 are also indicated. (C) Distamycin-[TAGGGTTA]4 (D2O). Cross-peaks are from left to right, A2 H8, A8 H8, A2 H2, A8 H2, DHF, G5 H8, T6 H6, T7 H6 and T1 H6. The resonance position of G4 H8 is also indicated.
