Description

Design a symmetric protein trimer, with 3 identical chains that assemble together! This puzzle uses the Buried Unsats Objective, which penalizes buried polar atoms that can't make H-bonds. 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! 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.

Buried Unsats (max +300)
Penalizes polar atoms that cannot make hydrogen bonds, -30 points per atom (not including symmetric copies).

Core Existence: Monomer (max +3000)
Ensures that at least 30 residues are buried in the core of the monomer unit.

Core: Complex (max +0)
Awards no bonuses or penalties. Click Show to see which residues count as "Core" for the H-bond Network objective.

H-bond Network (max +1800)
Rewards networks that comprise at least two H-bonds involving core residues.
Between 1 and 9 H-bonds should cross the interface between symmetric units.
Networks must be at least 75% satisfied (i.e. 75% of all bondable atoms in a network must make a H-bond).

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