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

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 8PSA entry

There are 3 chains in PDB entry 8PSA (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	MET 1	LYS 1886
B	ILE 140	LEU 302
G	SER 5	GLN 2050

There are166 helices in PDB entry 8PSA. Click on helix of interest for CSU analysis.
