This puzzle challenges players to design a single-chain protein with 75-90 residues. We've softened the penalties associated with the Core Existence filter, which have typically been very steep. 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. 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!

We are giving you a helix positioned over a hydrophobic groove where binding occurs in nature. You can mutate any residue on the helix but none on the native binding region. Try to look for favorable hydrophobic interactions in this groove while maintaining the helix. For players with fewer than 150 global points.

This is the first official small molecule design puzzle. The goal is to change the ligand in the center of the protein to find better inhibitors of HIV protease. Use the Ligand Design tool in the selection interface (or the "Ligand Design" mode in the original interface) to alter the chemical identity of the inhibitor. See the blog post for more information on the puzzle and small molecule design.

Chikungunya (CHIK-un-goon-ya) virus (also known as CHIKV) is a mosquito-transmitted alphavirus that has spread around the world and is currently infecting people in about 60 countries globally. CHIKV is rarely fatal, but causes severe joint pain for months to years that can debilitate affected patients for long periods of time. There are currently no known drugs to treat CHIKV infection, primarily due to a lack of understanding of the structure of CHIKV proteins involved in viral genome replication. The Geiss lab has worked on developing drug targeting the membrane bound CHIKV nsP1 protein, which is the anchor for the viral genome replication complex on cellular membranes and a multifunctional enzyme that forms a 5’ RNA cap structure on the end of the CHIKV RNA genome. Solving the structure of the CHIKV nsP1 protein would provide critical information for designing drugs that inhibit nsP1 function and abort viral genome replication.

In electron density puzzles, we give you some experimental data to help you find the correct fold. This data takes the form of an electron density, and appears in game as a guide. You can adjust the guide visualization by going to [Actions]>[Electron Density]. For players with fewer than 150 global points.

We are giving you this Parabacteroides Distasonis protein as an extended chain. The native is shown as a guide on this puzzle, so try using everything you have learned in the Intro levels to match the native fold. Hints and details are posted in the puzzle comments. For players with fewer than 150 global points.

This small unsolved Arabidopsis protein only has 59 residues and negatively controls the biosynthesis of starch in plants and regulates leaf and seed composition. We are giving you 5 starts for this puzzle. Resetting the puzzle will cycle through these 5 Zhang server predictions. They are also in the Alignment Tool so you can use partial threading as well as an extended chain. For players with fewer than 150 global points.

This is a small symmetric trimer design puzzle. A symmetric protein relies not only on how well folded each part is, but also on how well they interface together. Your changes will be reflected in the symmetric unit. Make sure you have completed Intro Puzzle 5-2, and 7-1 through 7-4. For players with fewer than 150 global points.
