蛋白质结构的几何和拓扑性质，包括表面口袋、内部空腔和交叉通道，对于蛋白质执行其功能是至关重要的。Computed Atlas of Surface Topography of Proteins（CASTp）是一个网络服务器，提供在线服务，用于定位，描绘和测量蛋白质结构的几何和拓扑特性。自2003年成立以来，它一直被广泛使用。在本文中，我们将介绍最新版本的Web服务器CASTp 3.0。CASTp 3.0继续提供可靠和全面的蛋白质拓扑结构鉴定和定量。此外，它现在提供：（i）口袋，空腔和通道的负体积的印记，（ii）蛋白质数据库中生物组件的地形特征，（iii）蛋白质结构和口袋的改进可视化，以及（iv）更直观的结构和注释信息，包括二级结构，功能位点，变异位点和蛋白质残基的其他注释信息。CASTp 3.0 Web服务器可在http://sts.bioe.uic.edu/castp/上免费访问。
Geometric and topological properties of protein structures, including surface pockets, interior cavities and cross channels, are of fundamental importance for proteins to carry out their functions. Computed Atlas of Surface Topography of proteins (CASTp) is a web server that provides online services for locating, delineating and measuring these geometric and topological properties of protein structures. It has been widely used since its inception in 2003. In this article, we present the latest version of the web server, CASTp 3.0. CASTp 3.0 continues to provide reliable and comprehensive identifications and quantifications of protein topography. In addition, it now provides: (i) imprints of the negative volumes of pockets, cavities and channels, (ii) topographic features of biological assemblies in the Protein Data Bank, (iii) improved visualization of protein structures and pockets, and (iv) more intuitive structural and annotated information, including information of secondary structure, functional sites, variant sites and other annotations of protein residues. The CASTp 3.0 web server is freely accessible at http://sts.bioe.uic.edu/castp/.
