Analysis of interatomic Contacts of Structural Units in PDB entry:
9XAB

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 9XAB entry

There are 22 chains in PDB entry 9XAB (CSU analysis of residue contacts immediately below table)
