研究动机：对蛋白-蛋白共结晶复合物和低分辨率蛋白-蛋白对接研究的观察表明，蛋白-蛋白复合物存在与结合相关的各向异性形状特征。结果：我们的研究通过测量表面残基到蛋白质质心的距离，系统地评估了共结晶蛋白质-蛋白质复合物的非冗余数据库中蛋白质的整体形状。结果表明，平均而言，结合位点残基比非结合表面残基更接近质心。因此，该研究直接检测了蛋白质形状的一个重要而简单的结合相关特征。结果提供了一个深入了解蛋白质结构和关联的基本性质之一。
Motivation: Observation of co-crystallized protein-protein complexes and low-resolution protein-protein docking studies suggest the existence of a binding-related anisotropic shape characteristic of protein-protein complexes.Results: Our study systematically assessed the global shape of proteins in a non-redundant database of co-crystallized protein-protein complexes by measuring the distance of the surface residues to the protein's center of mass. The results show that on average the binding site residues are closer to the center of mass than the non-binding surface residues. Thus, the study directly detects an important and simple binding-related characteristic of protein shapes. The results provide an insight into one of the fundamental properties of protein structure and association.
