Analysis of interatomic Contacts of Structural Units in PDB entry:
1ORW

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 1ORW entry

There are 4 chains in PDB entry 1ORW (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	SER 39	PRO 766
B	SER 39	PRO 766
C	SER 39	PRO 766
D	SER 39	PRO 766

There are 78 helices in PDB entry 1ORW. Click on helix of interest for CSU analysis.
