Buried Unsats (max +100)
Penalizes 60 points for each polar atom that cannot make any H-bonds. Note that the frozen target includes 15 buried unsats that may be impossible to satisfy.
Residue Count (max +275)
Penalizes extra residues inserted beyond the starting 151, at a cost of 55 points per residue. Players may use up to 156 residues in total.
Core Existence (max +1000)
Ensures that at least 25 percent of residues are buried in the core of the monomer unit.
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.
SS Design (max +500)
Penalizes all CYS residues. Penalizes GLY, ALA residues in sheets. Penalizes GLY, ALA, SER, THR in helices.
