Note: CEAlign is now built into PyMOL as a native command. See the open-source project page.
This page is the home page of the open-source CEAlign PyMOL plugin. The CE algorithm is a fast and accurate protein structure alignment algorithm, pioneered by Drs. Shindyalov and Bourne (See
References).
Introduction
There are a few changes from the original CE publication (See Notes). The source code is implemented in C (and another in C++) with the rotations finally done by Numpy in Python (or C++ in version 0.9). Because the computationally complex portion of the code is written in C, it's quick. That is, on my machines --- relatively fast 64-bit machines --- I can align two 400+ amino acid structures in about 0.300 s with the C++ implementation.
This plugs into PyMol very easily. See the code and examples for installation and usage.
