Welcome to RosettaBackrub

This is the flexible backbone protein structure modeling and design server of the Kortemme Lab. The server utilizes the "backrub" method, first described by Davis et al.1, for flexible protein backbone modeling implemented in Rosetta2,3,5,6,7.

The server input is a protein structure (a single protein or a protein-protein complex) in PDB format uploaded by the user or obtained directly from the PDB plus some application-specific parameters. The server output is dependent on the application:

  • Point mutation5: generates modeled structures and Rosetta scores for single and multiple point mutants in monomeric proteins;
  • Backbone ensemble2: creates near-native structural ensembles of protein backbone conformations (for monomeric proteins) and sequences consistent with those ensembles;
  • Sequence tolerance6,7,3: predicts sequences tolerated for proteins and protein-protein interfaces using flexible backbone design methods. Example applications are the generation of sequence libraries for experimental screening and prediction of protein or peptide interaction specificity.

For a tutorial on how to submit a job and interpret the results see the documentation and the references below. Please also check for current announcements.
