Conclusions:

  • Analytical calculation of the solvent accessible surface areas and their derivatives (ASAD) has been simplified due to the new vector parametrization.

  • CPU time spent on ASAD calculations can be greatly reduced by employing new algorithm of finding the vertices of Gauss-Bonnet path by calculating the intersection of half-spaces.

  • Protein-solvent interaction is an extraordinarily important factor in computational studies of protein folding. Energy minimization without solvent is successful in mathematical sense, but it does not allow one to find the native structure. On the other hand, inclusion of solvent smoothes low energy local minima for unfolded structures and therefore drives structure minimization towards a folded state.
