【授賞理由】

These days, molecular dynamics (MD) simulation becomes a useful and reliable tool to reveal the dynamic features of biological macromolecules, even when the static structures are known. In this article, the authors performed docking calculations for the two target proteins: one of GPCR membrane protein, β2 adrenergic receptor (β2AR), and a soluble protein, PR-Set7, which catalyzes the methylation of the H4 tail in the cell. For β2AR, the authors investigated the complex structures with the six ligand molecules, and for PR-Set7, they used two bound inhibitors. The former complex structures are rather rigid and, on the contrary, the latter ones are flexible. After all-atom MD simulations for longer than 100 ns, the trajectories for each MD run were calculated starting from the complex structures predicted with the docking software. The authors assessed the conventional docking predictions with MD simulations, and they show (1) for the rigid complex structures of β2AR with its ligands, the docking predictions could give the essential interactions and the MD simulations provide the details of the binding modes, depending on the individual ligand species, (2) for flexible complex structures of PR-Set7 with its ligands, the ligands greatly departed from the predicted docking poses during the MD simulations. Consequently, MD simulations can provide complementary information about the binding complex structure.
Thus, the authors succeeded in demonstrating that MD simulation can be used to assess binding structures predicted by docking, and to provide complementary information. They also found that stability of the predicted ligand pose was moderately correlated to ligand similarity. This article is, therefore, believed to pave the way for the reliable usage of MD simulation, in structural biology and applications to drug discovery.
