Analysis of interatomic Contacts of Structural Units in PDB entry:
8ERA

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 8ERA entry

There are 4 chains in PDB entry 8ERA (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	SER 17	TRP 2549
B	GLY 2	GLU 108
C	VAL 8	VAL 324
Y	GLU 18	GLU 1331

There are176 helices in PDB entry 8ERA. Click on helix of interest for CSU analysis.
