Wide Search Molecular Replacement
Wide Search Molecular Replacement (WSMR) performs a molecular replacement search with the application Phaser against approximately 100,000 SCOP domains. The search results are presented in the form of an LLG/TFZ graph and computations usually converge within 4-14 days. Before you submit your computations you will need to create an SBGrid portal account (request an account here) and upload your mtz file. Protein sequence files are not required. For a full description of this method please see our publication Stokes-Rees I and Sliz P, PNAS 2010. 107(50):21476-81.Launch Now
Deformable Elastic Network
Deformable Elastic Network (DEN) restraints are a powerful tool for refining structures from low-resolution X-ray crystallographic data sets. Our DEN web service provides access to resources for running computationally intensive DEN refinements in parallel on the Open Science Grid, a US cyberinfrastructure. Refinements combined with full parameter optimization that would take many thousands of hours on standard computational resources, can be completed in several hours using the DEN portal. For a full description of this service please see our publication O'Donovan D et. al, Acta Cryst. D. 2012. 68:261-7.Launch Now
Computations are performed using resources provided by the Open Science Grid, which is supported by the National Science Foundation and the US Department of Energy's Office of Science. Development of the portal was supported by the National Science Foundation grant 0639193.
