Free-energy perturbation calculations of DNA destabilization by base substitutions: the effects of neutral guanine.thymine, adenine.cytosine and adenine.difluorotoluene
Article Abstract:
A study is conducted to evaluate the solvation free energy cost associated with thymine (T) -> difluorotoluene (F), T -> cytosine (C) and C -> T transformation in aqueous solution and in a DNA duplex. The dependence of the calculated free energies on the DANA sequence, the simulation length, size of the water droplet and phosphate charges are examined.

Ab initio evaluation of the free energy surfaces for the general base/acid catalyzed thiolysis of formamide and the hydrolysis of methyl thiolformate: a reference solution reaction for studies of cysteine proteases
Article Abstract:
A study is conducted to understand the quantitative relevant energetics of the catalytic reaction of cysteine proteases and the free energy surface for the corresponding reference solution reaction is determined. The calculations involve self-consistent evaluation of the solute charges in solution as \well as mapping the solution free energy surface.
