Free energy approximations in simple lattice proteins

Reith, Dirk; Huber, Thomas; Mueller-Plathe, Florian; Torda, Andrew E.


This work addresses the question of whether it is possible to define simple pair-wise interaction terms to approximate free energies of proteins or polymers. Rather than ask how reliable a potential of mean force is, one can ask how reliable it could possibly be. In a two-dimensional, infinite lattice model system one can calculate exact free energies by exhaustive enumeration. A series of approximations were fitted to exact results to assess the feasibility and utility of pair-wise free...[Show more]
