Description

Note: This puzzle was closed early due to an error that prevented players from opening the puzzle. The puzzle has been reposted as Puzzle 1619b.



This symmetric design puzzle has C3 symmetry, with three symmetric chains. The H-bond Network Objective encourages players to bury H-bond Networks at the interface between the two chains. We've doubled the H-bond Network bonus, but we'd like players to focus on building networks deep in the core of the protein complex. There are a couple other bonuses in effect; see the puzzle comments for 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!

Core Existence: Monomer (max +3000)
Ensures that at least 21 residues are buried in the core of the monomer unit. The threshold of "buriedness" between core and surface residues is more stringent than usual, so residues may have to be "extra buried" to be counted toward the core.

Core Existence: Complex (max +4650)
Ensures that at least 72 residues are buried in the core of the entire complex (including the interface between monomer units).

HBond Network
Rewards networks that comprise at least three hydrogen bonds involving core residues. Networks must be at least 70% satisfied (i.e. 70% of all oxygens and polar hydrogens in a network must make a hydrogen bond).

SS Design (max +500)
Prohibits all CYS residues. Prohibits GLY, ALA residues in sheets and helices.

Ideal Loops (max +500)
Penalizes any loop region that does not match one of the Building Blocks in the Blueprint tool. Use "Auto Structures" to see which regions of your protein count as loops.

I get a message when opening this puzzle and it remains stuck on loading.

Anchor residue 91 is not rooted at pose.total_residue() 77

The last trimer puzzle crashed several times mid script. Once it was running local quake with mutate, once I think dremix. It was very frustrating as it limited the time I had to work with any shape I tried. Might be too big for my machine
