Questions that can be answered in such an approach, using large numbers of repeated docking calculations, are: What are the conformation binding modes of a small molecule to a protein cavity What are the energy estimates and thermality of these binding modes Which atoms are important in the binding and which aren't What is the flexibility of the epitope, quantitatively, in its bound conformation in the cavity What is the entropy loss from reduced number of rotatable bonds in binding What is the probability of the small molecule in one conformation versus another What is a quantitative estimate of the bound-state lifetime These questions and others can be answered in different levels of detail using docking distributions and analysis. The approach of multiple docking calculations gives similar information to an MD simulation of a protein conformation, using for example MMGBSA or MMPBSA, but is orders of magnitude times quicker computationally. These questions are important to answer for general understanding of specific protein-ligand or proteincarbohydrate interactions. Computationally the information is necessary in molecular design and its applications, and in drug design to hit identification and hit-to-lead optimization.
