Analysis of interatomic Contacts of Structural Units in PDB entry:
7XA7

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 7XA7 entry

There are 3 chains in PDB entry 7XA7 (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	SER 2	SER 597
B	ASN 334	LYS 528
C	SER 2	LYS 441

There are160 helices in PDB entry 7XA7. Click on helix of interest for CSU analysis.
