提出了一种预测配体与蛋白质结合亲和力的方法。我们首先通过复制交换伞采样或其推广预测了蛋白质-配体复合物的结构。然后,我们计算配体结合亲和力的基础上,这些预测的配体-蛋白质结合结构的双重解耦方法。为了验证所提出方法的有效性,我们将其应用于癌蛋白MDM 2和配体的系统。预测的结合亲和力的值被证明是在良好的协议从实验。
A prediction method for ligand binding affinities to proteins is proposed. We first predict the structures of protein–ligand complex by the replica-exchange umbrella sampling or its extension. We then calculate ligand binding affinities based on these predicted ligand–protein bound structures by the double-decoupling method. As a test of the effectiveness of the proposed method, we applied it to the system of the oncoprotein MDM2 and a ligand. The value of the predicted binding affinity turned out to be in good agreement with that from experiments.
