Foldit Puzzles

1202: 75 Residue Monomer Design

This is a basic 75 residue design puzzle with slightly up-weighted ideality scoring. Players should take care that all cutpoints are closed with good geometry! See the puzzle comments for filter details. The Baker Lab will run folding predictions on your solutions for this puzzle, and those that perform well will be synthesized in the lab. Remember, you can use the Upload for Scientists button for up to 5 designs that you want us to look at, even if they are not the best-scoring solutions!

1201: Revisiting Puzzle 140: Rosetta Decoy 4

This is a throwback puzzle to the early days of Foldit. This protein helps to regulate oxidation in the cell; the starting structure is a model produced by Rosetta. This protein contains four cysteine residues, but in this state only two of them are expected to oxidize to form a single disulfide bond. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1200: Unsolved De-novo Freestyle 71

The structure of this protein is still unknown. Secondary structure predictions (from PSIPRED) are marked on the starting structure, and provide clues about where the protein might form helices and sheets!

1199: 70 Residue Monomer Design

This is a basic 70 residue design puzzle with slightly up-weighted backbone scoring. Players should take care that all residues have a good backbone score! See the puzzle comments for filter details. The Baker Lab will run folding predictions on your solutions for this puzzle, and those that perform well will be synthesized in the lab. Remember, you can use the Upload for Scientists button for up to 5 designs that you want us to look at, even if they are not the best-scoring solutions!

1198: Revisiting Puzzle 139: Rosetta Decoy 3

This is a throwback puzzle to the early days of Foldit. Ubiquitin is a well-known protein that helps to regulate the natural turnover of proteins in the cell, and this starting structure is a model of the protein produced by Rosetta. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1197: Unsolved De-novo Freestyle 70

The structure of this protein is still unknown. Secondary structure predictions (from PSIPRED) are marked on the starting structure, and provide clues about where the protein might form helices and sheets!

1196: 70 Residue Monomer Design: More Sheets!

This is a basic 70 residue design puzzle without any Fragment Filter. See the puzzle comments for filter details. The Baker Lab will run folding predictions on your solutions for this puzzle, and those that perform well will be synthesized in the lab. Remember, you can use the Upload for Scientists button for up to 5 designs that you want us to look at, even if they are not the best-scoring solutions!

1195: Revisiting Puzzle 138: Rosetta Decoy 2

This is a throwback puzzle to the early days of Foldit. Ubiquitin is a well-known protein that helps to regulate the natural turnover of proteins in the cell, and this starting structure is a model of the protein produced by Rosetta. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

1194: Unsolved De-novo Freestyle 69

The structure of this protein is still unknown. Secondary structure predictions (from PSIPRED) are marked on the starting structure, and provide clues about where the protein might form helices and sheets!

1193: UMich Challenge: Refined Density

This puzzle is a followup to Puzzle 1152: Foldit vs. UMich Electron Density Challenge. We were impressed with many players' solutions, and our UMich collaborators have a shared a higher resolution dataset of the same protein. Foldit solutions were used to develop a higher quality electron density map from the new dataset, and we’d like to see if players can use it to further improve this model! Pay special attention to residues 20-32 and 51-64, which were unresolved in Puzzle 1152. Note that players will not be able to load in solutions from Puzzle 1152.
