THIS IS A MULTISTART PUZZLE - Click "RESET PUZZLE" to cycle through both starting structures. CASP14 has released another refinement target with 2 different starting structures. They did not reveal the accuracy of either starting model, but we do know that they are both incorrect. Try to explore far enough away from both starting structures, as the highest-scoring folds might be far away from both starts!

Design a binder against coronavirus! We saw some great looking designs in the previous Round 12 puzzle; we want to see even more! This puzzle is set up exactly like Round 12, and we'd like players to keep focusing on making closely packed interfaces with no extra BUNS. If your designed protein creates Buried Unsats, then it will be less likely to fold and bind to the coronavirus target. (Note that this target protein includes 8 buried unsats that players may be unable to fix.) See the blog for more details about buried unsats, and for helpful tips to make a successful protein binder! Players may not load solutions from previous puzzles.

Design a symmetric protein trimer, with 3 identical chains that assemble together! This puzzle uses the Buried Unsats Objective, with a large penalty for buried polar atoms that can't make H-bonds. The H-bond Network Objective encourages players to build buried, satisfied H-bond networks at the interface between symmetric chains. H-bond networks are a great way to introduce polar residues at the interface, but it's important that all of the bondable atoms make hydrogen bonds! In this puzzle, there are no limits on the Complex Core, but we've included the Complex Core objective so players can see the core residues that can be incorporated into H-bond Networks.

Design an anti-inflammatory protein for COVID-19! The Buried Unsats Objective has been reactivated and it will incur a 60 pt penalty for each BUNS atom. If your designed protein creates Buried Unsats, then it will be less likely to fold and bind to the target. (Note that this target protein includes 15 buried unsats that players may be unable to fix.) See the blog for more details about buried unsats, and for helpful tips to make a successful protein binder! Players will be unable to load solutions from previous puzzles.

CASP14 has released this refinement target with this additional explanation: "Hard refinement target. Starting model's GDT_HA=28." This means that less than one third of this starting model matches the unreleased native structure. Try exploring as far as you can from the starting structure!

Design a binder against coronavirus! Now the Buried Unsats Objective has been reactivated and will incur a 60 pt penalty for each BUNS atom. If your designed protein creates Buried Unsats, then it will be less likely to fold and bind to the coronavirus target. (Note that this target protein includes 8 buried unsats that players may be unable to fix.)

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 and to provide newer players with puzzles that are still scientifically relevant.
