This is our second puzzle featuring the new Hydrogen Bond Network filter. This puzzle contains two chains, however they are not symmetric—players will need to design both sides of the interface between the two chains! We've provided you with a fixed backbone that can make a number of HBond networks. Mutate the sequence to form HBonds between the Red and Blue polar atoms on the sidechains. Be sure to check out the recent blog post for more information!

This puzzle uses a more stringent fragment filter than previous design puzzles. 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 eelpout protein binds nucleated ice crystals to inhibit their growth. 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 small peptide was discovered in platypus venom—a rare instance of mammalian-produced venom, although this peptide appears similar to more widespread antimicrobials. This protein contains six cysteine residues that oxidize to form three disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

Players folded the N-terminal half of the protein previously in Puzzle 1088; in this puzzle we'll focus on the C-terminal half of the protein. The starting solution is based on the structure of a homologous protein. See if you can find a solution that better fits the density!

Click the "Show" checkbox beneath the Core Existence filter to see which residues have been identified as Core (orange), Boundary (green), or Surface (blue). There are several other filters in effect; see the puzzle comments for details.

This is a throwback puzzle to the early days of Foldit. This domain is a component of a large glycoprotein in humans, which has been linked to autosomal dominant polycystic kidney disease. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

The full protein is too large to model in Foldit, so we'll approach it in two separate puzzles; in this puzzle we'll focus on the N-terminal half of the protein. The starting solution is based on the structure of a homologous protein. See if you can find a solution that better fits the density!
