Extended Data Figure 3. New backbone modeling tools in Foldit.

a, The Remix tool allows players to select a region of the model and search a library of backbone fragments for a conformation that can be substituted. b, An interactive Ramachandran map allows players to easily identify residues with outlier backbone conformations. Players can also click-and-drag points on the Ramachandran map to set the backbone torsions of individual residues. c, A Blueprint panel shows the primary sequence and secondary structure content of the model. Residues are colored according to the ABEGO quadrants of the Ramachandran plot⁷. d, Players can drag-and-drop modular Building Blocks onto the Blueprint panel to insert common turn conformations into their model.
