The influence of Mn2+ions on the structure of natural calf thymus DNA was studied by Raman spectroscopy. Measurements were done at room temperature and pH 6.2±0.2, in the presence of the physiological concentration of 150 mM Na+ions, and in the presence of Mn2+concentrations that varied between 0 and 600 mM. No condensation of DNA was observed at any of the Mn2+concentrations. At 5 mM Mn2+and 150 mM Na+no significant influence of Mn2+ions on the DNA structure can be observed. Compared with our previous results obtained at 10 mM Na+ions, binding of Mn2+ions to charged phosphate groups and to DNA bases is inhibited in the presence of 150 mM Na+ions. DNA backbone conformational changes were not observed in the whole concentration range of Mn2+ions as judging from the Raman spectra. No evidence for DNA melting was identified. A high Mn2+affinity for binding to guanine N7 and possibly, in a much lesser extent, to adenine have been found.
