Description

This puzzle is similar to recent design puzzles except that we've restricted the use of SER and THR residues in α-helices. Foldit players have submitted some stellar-looking designs recently, but we are seeing quite a lot of SER and THR residues in designed helices. Recent experiments in our lab suggest that these residues are somewhat unfavorable in helices, so in this puzzle we've restricted the use of SER and THR in helical positions. 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!

Residue IE Score: Monitors that all PHE, TYR, and TRP residues are scoring well.

Core Existence: Ensures that at least 30% of the residues are buried in the core of your design.

Secondary Structure: Checks that no more than 50% of residues are in helices; penalties are incurred if more than 50% of residues form helices.

Secondary Structure Design: Penalizes all CYS residues. Penalizes GLY, ALA residues in sheets; penalizes GLY, ALA, SER, THR in helices.

Residue Count: Penalizes extra residues inserted beyond the 90 residue limit. Players may insert up to 10 extra residues.

Ideal Loops: Penalizes loops that do not conform to preferred ABEGO patterns. Use Auto Structures to see which residues count as "loops."
