Analysis of interatomic Contacts of Structural Units in PDB entry:
7K3Z

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 7K3Z entry

There are 3 chains in PDB entry 7K3Z (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	LYS 68	GLU 631
B	GLY 69	GLU 631
C	GLY 69	ALA 229

There are161 helices in PDB entry 7K3Z. Click on helix of interest for CSU analysis.
