Interatomic contacts.


This server calculates contacts between all atoms in your PDB file, including water. All contacts are listed only once. Symmetry contacts are excluded. Contact distance 0.25 Ångstrom.


A contact is defined as two atoms for which the distance between the Van der Waals surfaces is less than 0.25 Ångstrom.
WHAT IF uses the following Van der Waals radii: C:1.8 Ångstrom; O:1.4 Ångstrom; N:1.7 Ångstrom; S:2.0 Ångstrom.
