The Phyre2.2 webserver has been developed by Harry Powell from the Phyre2 webserver which was designed and written by Dr Lawrence Kelley

Phyre2 is the successor to the two web servers that Lawrence previously developed, 3D-pssm and Phyre. Phyre2 was ranked amongst the best systems of its kind as judged by the biannual Critical Assessment of Structure Prediction (CASP) meetings, prior to the release of the original AlphaFold in 2018.

The work on developing the Phyre2 web server is supported by a BBSRC tools and resources grant
