Analysis of interatomic Contacts of Structural Units in PDB entry:
1WSA


Contacts of Structural Units (CSU) are derived with the CSU software (Sobolev V., Sorokine A., Prilusky J., Abola E.E. and Edelman M. (1999) Automated analysis of interatomic contacts in proteins. Bioinformatics, 15, 327-332).
For CSU analysis of other PDB entry

This page provides analyses of contacts formed by:
For analysis of ligand-protein contacts, use: 3D structure can be seen in additional window with STING software for 1WSA entry

There are 2 chains in PDB entry 1WSA (CSU analysis of residue contacts immediately below table)
