Molecular mechanics—Poisson Boltzmann surface area approach

Another methodological approach, which has become more attractive in the last few years for estimating binding free energies of protein-protein complexes, is the MM-PBSA method (Molecular Mechanics/Poisson-Boltzmann Surface Area). This method is a fully atomistic approach that combines molecular mechanics and continuum solvent, and has several appealing features as the possibility of being applied to a variety of systems not suitable for FEP such as very large protein-protein complexes.69,129-137...
