Analyse Protein - Cofactor Contacts


This server calculates contacts between macromolecules (protein and nucleic acids) at the one hand and co-factors, ligands, drugs and ions at the other.


A contact is defined as two atoms for which the distance between the Van der Waals surfaces is less than 1.0 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.
