The present invention is directed to serve ligand screening apparatuses, ligand screening methods, programs and recording medium for studying the binding analysis between a receptor including an induced-fit type receptor and a ligand. First, analysis and calculation of normal mode are conducted, and then fluctuation of dihedral angle of main chain in a steady state is calculated. Then by carrying out molecular dynamic calculation while imposing constraint on each atom based on the fluctuation, dynamic structure of the receptor is predicted more accurately. By using the dynamic structure obtained in the molecular dynamic calculation and an interaction function, receptor/ligand binding which is also applicable to an induced-fit type receptor is predicted with high accuracy.
本发明涉及配体筛选装置、配体筛选方法、程序和记录介质,用于研究包括诱导拟合型受体在内的受体与配体之间的结合分析。首先进行法向模式分析和计算,然后计算稳定状态下主链二面角的波动。然后进行分子动力学计算,同时根据波动对每个原子施加约束,从而更准确地预测受体的动态结构。利用分子动力学计算得到的动态结构和相互作用函数,可以高精度地预测受体与配体的结合,这种结合也适用于诱导拟合型受体。
