For example, hundreds of thousands of computers are used for running docking in and similar projects. One is interested in maximizing the accuracy of these predictions while minimizing the computer time they take, since the computational resources spent on docking are considerable. Docking can also be used to try to predict the bound conformation of known binders, when the experimental holo structures are unavailable. The prediction of binding of small molecules to proteins is of particular practical importance because it is used to screen virtual libraries of drug-like molecules in order to obtain leads for further drug development. The goal is to predict the bound conformations and the binding affinity. Molecular docking is a computational procedure that attempts to predict noncovalent binding of macromolecules or, more frequently, of a macromolecule (receptor) and a small molecule (ligand) efficiently, starting with their unbound structures, structures obtained from MD simulations, or homology modeling, etc. ![]()
