Resolving the problem of trapped water in binding cavities : prediction of host–guest binding free energies in the SAMPL5 challenge by funnel metadynamics
The funnel metadynamics method enables rigorous calculation of the potential of mean force along an arbitrary binding path and thereby evaluation of the absolute binding free energy. A problem of such physical paths is that the mechanism characterizing the binding process is not always obvious. In particular, it might involve reorganization of the solvent in the binding site, which is not easily c
