MultiFOLD: automated prediction, quality assessment and refinement of tertiary and quaternary structure models of proteins

About the server

The MultiFOLD server provides:

  1. State-of-the-art prediction of both tertiary and quaternary structures of proteins.
  2. Integrated predictions of both global and local model quality for the top refined models.
  3. Interactive 3D views of predicted multimeric assemblies which can be coloured by chain ID or accuracy.
  4. Machine-readable data downloads.
