Description:

The software tool, BetaTurn18 reads a protein structure in mmCIF or PDB format, locates beta turns and assigns their types using our 2018 library, BetaTurnLib18 with 18 beta-turn types. BetaTurnLib18 includes conformational centroids and medoids of 18 beta-turn types. It is provided in 3 formats: a plain-text tab-delimited file, PDF and XLSX spreadsheet.

Both the beta-turn tool and library can be downloaded for further use in third-party tools and software. The tool and library are free, open-source, redistributable and modifiable under BSD 3-Clause License. We adopted the software for 3 operating systems: Unix, Mac and Windows. It automatically downloads required Python tools. The only requirement is to have python2 installed.

Download:

Download of BetaTurn18 and BetaTurnLib18 and their included instructions on how to use are available here on this website and also on GitHub/BetaTurn18.
