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 symmetric design puzzle has C2 symmetry, with two symmetric chains. The H-bond Network Filter encourages players to bury satisfied H-bond networks at the interface between the two chains. There a couple other filters in effect; see the puzzle comments for 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 helps to transfer electrons between substrates in bacteria. The protein is modeled here in reducing conditions, and no disulfides are expected to form. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

This is a throwback puzzle to the early days of Foldit. This human protein helps to regulate the reduction potential of the cell, and should be modeled here in reduced form (with no disulfide bonds). 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 85-105 residues. The starting structure has 85 residues, but more can be added at a cost of 32 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!

Note: Due to player reports of persistent crashing, this puzzle is now worth zero points, so players may skip this puzzle without any effect on their rankings. However, if players would like to continue playing the puzzle, we will still analyze the puzzle solutions. And of course, we appreciate all of the detailed feedback about the puzzle!

This is a throwback puzzle to the early days of Foldit. This spinach protein is critical for photosynthesis, and participates in the electron transfer chain within the chloroplast. The protein is modeled here in the reduced state, so no disulfides are expected to form. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

Note: This puzzle replaces the original Puzzle 1515, which was posted with an erroneous Residue Count Filter. Players may load their saved work from the original Puzzle 1515.
