Table 1 Distance criteria (in Å) and physicochemical types of atoms involved in each type of interaction
Type of interaction | Atom types | Minimum distance | Maximum distance |
|---|---|---|---|
Aromatic stacking | Two aromatic atoms | 1.5 | 3.5 |
Hydrogen bond | An acceptor and a donor atom | 2.0 | 3.0 |
Hydrophobic | Two hydrophobic atoms | 2.0 | 3.8 |
Repulsive | Two atoms with the same charge | 2.0 | 6.0 |
Salt bridges | Two atoms with opposite charge | 2.0 | 6.0 |
