X-ray crystallography is the most widely used method to determine the 3D structure of protein molecules. One of the most difficult steps in protein crystallography is model-building, which consists of constructing a backbone and then amino acid side chains into an electron density map. Interpretation of electron density maps represents a major bottleneck in protein structure determination pipelines, and thus, automated techniques to interpret maps can greatly improve the throughput. We have developed WebTex, a simple and yet powerful web interface to TEXTAL, a program that automates this process of fitting atoms into electron density maps. TEXTAL can also be downloaded for local installation.

X射线晶体学是确定蛋白质分子三维结构最广泛使用的方法。蛋白质晶体学中最困难的步骤之一是模型构建，它包括构建主链，然后将氨基酸侧链放入电子密度图中。电子密度图的解释是蛋白质结构测定流程中的一个主要瓶颈，因此，解释图谱的自动化技术可以大大提高通量。我们开发了WebTex，这是一个简单而强大的TEXTAL网络界面，TEXTAL是一个将原子拟合到电子密度图的自动化程序。TEXTAL也可以下载进行本地安装。
