Abstract :

Precise determination of interaction networks of target-ligand interfaces is a pre-requisite of structure-based drug design. Crystallography and other methods produce high quality target-ligand structures at an increasing rate. However, development of calculation techniques for the interface structure is necessary for drug design projects with thousands of candidate ligands. In many cases, interactions between the target and ligand molecules are mediated by numerous water molecules filling the space and bridging between the two partners. Determination of the position of such mediating water molecules in the target-ligand interface is very challenging due to their mobility and promiscuous interaction profile. To overcome the limitations of rational design related to such structural uncertainty of hydration, we develop a new technique for the determination of the position of essential water molecules in the binding interface. The technique will be useful for precise calculation of hydration networks of molecular interfaces helping further calculations of binding thermodynamics of target-ligand complexes. It will be also useful for experimentalists helping the assignation of positions of water molecules in problematic situations.
