Abstract

Graphical abstract: Highlights: Water is essential in binding sites and to mediate interactions to ligands. Displacement of water by ligands affects free binding energy of complexes. Identifying localized water to be displaced by a ligand is important for design. Interesting computational approaches here include WaterMap and 3D RISM. Abstract: Water is an essential part of protein binding sites and mediates interactions to ligands. Its displacement by ligand parts affects the free binding energy of resulting protein-ligand complexes. Therefore the characterization of solvation properties is important for design. Of particular interest is the propensity of localized water to be favorably displaced by a ligand. This review discusses two popular computational approaches addressing these questions, namely WaterMap based on statistical mechanics analysis of MD simulations and 3D RISM based on integral equation theory of liquids. The theoretical background and recent applications in structure-based design will be presented.
