This puzzle challenges players to design a single-chain protein with 65-75 residues. We've adjusted the scoring function here so that alanine residues are more tolerable in loops (they are still restricted in helices and sheets!). The starting structure has 65 residues, but more can be added at a cost of 23 points per residue. 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!

Focus on your early game as we revisit puzzle 1381: Unsolved De-novo Freestyle 105. In this Sketchbook puzzle, you have 250 moves at your disposal. Once you use them up, you can reset and try something else!

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!

This puzzle challenges players to design a single-chain protein with 95-120 residues. The Core Existence filter has been escalated so that 40% of residues need to be buried in the protein core. The starting structure has 95 residues, but more can be added at a cost of 23 points per residue. 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!

This is a throwback puzzle to the early days of Foldit. This protein comes from the bacteria Escherichia coli, but its function is still unknown! We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

This puzzle challenges players to design a single-chain protein with 75-90 residues. The Core Existence filter has been escalated so that 35% of residues need to be buried in the protein core. The starting structure has 75 residues, but more can be added at a cost of 23 points per residue. 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.

This is a throwback puzzle to the early days of Foldit. This protein shuttles lipids between cell membranes in the rice plant. The protein contains eight cysteines that oxidize to form four disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.
