The effect of spermine binding on the electrostatic potential of DNA is evaluated. The calculations are performed for the essential reactive sites, atoms N7 and O6 of guanine, N3 and N7 of adenine, of the nucleic acid and for its surface envelope. An important weakening of the potential is found affecting all the important reactive sites in both grooves and spreading moreover along the polynucleotide chain far away from the site of binding of the ligand. These results are discussed in connection with the experimentally observed inhibitory effect of spermine binding on DNA methylation by carcinogenic agents.
