Residue IE Score: Monitors that all PHE, TYR, and TRP residues are scoring well.
HBond Network: Rewards networks comprising at least three hydrogen bonds. Up to 6 hydrogen bonds may span all interfaces. In addition, at least 75% of all polar atoms in a network must make hydrogen bonds.
Core Existence: Monomer: Ensures that at least 18 residues are buried in the core of the monomer unit.
Core Existence: Complex: Ensures that at least 66 residues are buried in the core of the entire complex (including the interface between monomer units).
