The ReFOLD server: refinement of 3D models of proteins guided by accurate quality estimates

About the server

The ReFOLD server provides:

  1. Refinement of 3D models of proteins and an assessment of their global quality.
  2. Interactive 3D comparisons of refined and original models
  3. Predictions of the local quality (per-residue error) within multiple refined models.
  4. Machine-readable data downloads

Example of ReFOLD quality assessment guided refinement for CASP12 target T0892 domain 1. Using ReFOLD we improved upon the initial server model (GDT_TS score improved from 79.71 -> 82.25). Left panel - starting model in cyan, refined model in magenta, actual structure in green. Right panel - GDT plot showing the improvement starting from initial server models (cyan) to the ReFOLD refined models (magenta).
