FoldDesign is a fragment-based approach to de novo protein scaffold design. Starting from the desired secondary structure and any user-defined contact or distance restraints, FoldDesign first identifies 1-20 residue fragments from the PDB that match the desired secondary structure. Following fragment generation, REMC simulations guided by a sequence-independent energy function are used to construct designable scaffolds that match the input constraints. Finally, the generated structure decoys are clustered and the final designs are selected from the lowest energy structures and largest cluster centers, where further atomic refinement and sequence design is then carried out on the selected designs.

The FoldDesign server takes as input the desired 3-state secondary structure, as well as an email address to inform a user when their job has finished running. Additionally, you may specify inter-residue contact or distance restraints.
The output of the server consists of:
(a) The final designed structures, where a download link is provided underneath the graphic. Designs are selected from the lowest energy designs as well as the largest cluster center. Additionally, users may download all structures generated during the FoldDesign simulations.
(b) The input secondary structure.
