DNA structure at low pH values, in the presence of Mn2+ ions: a Raman study

Raman spectra of calf thymus DNA were measured in the pH interval 6.4 to 3.45 in the presence of divalent manganese ions. pH‐dependent protonation of AT and GC base pairs and conformational changes were indicated in the spectra. Protonation of adenine residues becomes obvious at pH 4.4 and continues...
