Analysis of interatomic Contacts of Structural Units in PDB entry:
4HNT

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 4HNT entry

There are 2 chains in PDB entry 4HNT (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	GLN 36	ASN 1093
B	GLN 36	GLU 319

There are193 helices in PDB entry 4HNT. Click on helix of interest for CSU analysis.
