Analysis of interatomic Contacts of Structural Units in PDB entry:
3ZEF

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 3ZEF entry

There are 4 chains in PDB entry 3ZEF (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	ASN 2	PRO 355
B	SER 883	HIS 2387
D	ASN 2	PRO 355
E	SER 883	SER 2396

There are149 helices in PDB entry 3ZEF. Click on helix of interest for CSU analysis.
