Note: This replaces the original LCB1 puzzle, which had some incorrect settings for Core Exists, Ideal Loops, and SS Design Objectives.

CASP14 has released this refinement target without any accuracy estimates, so we're unsure how well the starting structure matches the native structure. Look for better scoring folds to find the true native structure!

Design an anti-inflammatory protein for COVID-19! We'd like players to keep focusing on making closely-packed interfaces with no extra Buried Unsats. This puzzle prohibits SER and THR in helices, which may make it harder to satisfy BUNS, but should help the helices to fold correctly. Remember, 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.

Design a symmetric protein trimer, with 3 identical chains that assemble together! 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! We've made a subtle change to the scoring of H-bonds that should help to improve H-bond geometry for SER, THR, and TYR sidechains. We've also adjusted the H-bond Network Objective so that poor-scoring H-bonds may not contribute to networks; poor-scoring H-bonds will be displayed in red. This puzzle uses the Buried Unsats Objective, with a large penalty for buried polar atoms that can't make H-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.

CASP14 has released this refinement target with starting model's GDT_HA=70. This means that about 70% of the starting structure matches the native structure. Look for better scoring folds to find the true native structure!

Design a binder against coronavirus! This puzzle introduces new binder metrics to measure the DDG, SASA, and Shape Complementarity of your design. Because the metrics are slow and must be run manually, they are available as optional Objectives and will not award any bonuses or penalties. To calculate these metrics, open the Objectives dropdown panel and click "Run All." Other Objectives are still in effect. This puzzle prohibits SER and THR in helices, which may make it harder to satisfy BUNS, but should help the helices to fold correctly. Remember, 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.
