Analysis of interatomic Contacts of Structural Units in PDB entry:
6PK4

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).
This page provides analyses of contacts formed by:

chains
helices
sheets
residues

For analysis of ligand-protein contacts, use:

LPC software

3D structure can be seen in additional window with STING software for 6PK4 entry

There are 4 chains in PDB entry 6PK4 (CSU analysis of residue contacts immediately below table)
