 要旨: Rigid body docking approaches are not sufficient to predict the structure of a protein complex from the unbound (native) structures of the two proteins. Accounting for side—chain flexibility is an important step towards fully flexible protein docking. This work describes an approach that allows conformational flexibility for the side—chains while keeping the protein backbone rigid. Starting from candidates created by a rigid docking algorithm, we demangle the side—chains of the docking site, thus creating reasonable approximations of the true complex structure. These structures are ranked with respect to the binding free energy. We present two new techniques for side—chain demangling. Both approaches are based on a discrete representation of the side—chain conformational space by the use of a rotamer library. This leads to a combinatorial optimization problem. For the solution of this problem we propose a fast heuristic approach and an exact, albeit slower method using branch—&—cut techniques. As a test set we use the unbound structures of three proteases and the corresponding protein inhibitors. For each of the examples the highest—ranking conformation produced was a good approximation of the true complex structure.
