The effects of Ru(NH3)(3+)6 on the conformation of poly(dG-m5dC).poly(dG-m5dC) and poly(dG-dC).poly(dG-dC) were studied by circular dichroism (CD) spectroscopy. Ru(NH3)(3+)6 at very low concentrations provokes the Z-DNA conformation in both polynucleotides. In the presence of 50 mM NaCl, the concentration of Ru(NH3)(3+)6 at the midpoint of B to Z transition of poly(dG-m5dC).poly(dG-m5dC) is 4 microM compared to 5 microM for Co(NH3)(3+)6. The half-lives of B to Z transition of poly(dG-m5dC).poly(dG-m5dC) in the presence of 10 microM Ru(NH3)(3+)6 and Co(NHG3)(3+)6 are at 23 and 30 min, respectively. The concentration of Ru(NH3)(3+)6 at the midpoint of B to Z transition of poly(dG-dC).poly(dG-dC) is 50 microM. These results demonstrate that Ru(NH3)(3+)6 is a highly efficient trivalent cation for the induction of B to Z transition in poly(dG-m5dC).poly(dG-m5dC) and poly(dG-dC).poly(dG-dC). In contrast, Ru(NH3)(3+)6 has no significant effect on the conformation of calf thymus DNA, poly(dA-dT).poly(dA-dT) and poly(dA-dC).poly(dG-dT).
