The interaction of Mg2+, Ca2+, Zn2+, and Cd2' with calf thymus DNA has been investigated by Raman spectroscopy. These spectra reveal that all of these ions, and particularly Zn2+, bind to phosphate groups of DNA, causing a slight structural change in the polynucleotide at very small metal : D N A (
The localization of the water-soluble cationic porphyrin ZnTMpyP(4) [Zn(II) derivative of 5,10,15,20-tetrakis(4-N-methylpyridyl)porphyrin] in its complex with [poly(dG-dC)] 2 is studied as a function of the solution ionic strength ( ฯญ 0.20 -0.03). It is shown that the position of the Soret band maxi
