The biologically important tautomerization of the Hyp . Cyt , Hyp * . Thy and Hyp . Hyp base pairs to the Hyp * . Cyt * , Hyp . Thy * and Hyp * . Hyp * base pairs , respectively , by the double proton transfer ( DPT ) was comprehensively studied in vacuo and in the continuum with a low dielectric constant ( epsilon = 4 ) corresponding to hydrophobic interfaces of protein - nucleic acid interactions by combining theoretical investigations at the B3LYP / 6 - 311 + + G ( d , p ) level of QM theory with QTAIM topological analysis .
