Analysis of interatomic Contacts of Structural Units in PDB entry:
7S2X

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 7S2X entry

There are 3 chains in PDB entry 7S2X (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	TYR 9	TRP 597
B	PRO 11	TRP 597
C	PRO 11	VAL 141

There are106 helices in PDB entry 7S2X. Click on helix of interest for CSU analysis.
