Description

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.

These puzzles have a problem.
They don't seems to allow 360 degree rotation.
They are very madding to work on.

Can you share your solution with scientists? There may be a bug, and that should help us track it down.

The puzzle configuration is definitely set to max out at +3000/+4650 pts for the Monomer/Complex objectives.

This is also odd. Both the Rama Map and Blueprint Tool should be available, and I can use them just fine here. Are other people also seeing this issue?

Can you say more about the rotation problem?

Do you mean you're having trouble rotating the camera (by clicking and dragging the background)? Or are you having trouble rotating the protein (using the move tool)?

Does the client crash, or do the tools stop working while Foldit continues to run?

Can you share your solution with scientists? This seems like a bug; those objectives should max out at +3000 and +4650.
