TABLE 2
Conformational parameters of the TGGCCADNA stretch in the (chromomycin A3)2·d(TTGGCCAA)2 and (trabectedin)2-d(GTATGGCCATAC)2 complexes, in comparison with regular A-DNA and B-DNA For (Chromomycin A3)2·d(TTGGCCAA)2, measured and averaged for the TGGCCA sequence in the two X-ray crystal structures present in PDB entry 1VAQ. For (trabectedin)2-d(GTATGGCCATAC)2, the energy-minimized average structure for TGGCCA was obtained from the last 4 ns of the MD simulations. Mean values for A- and B-DNA from X-ray crystal structures (Ng et al., 2000).
