Analysis of interatomic Contacts of Structural Units in PDB entry:
3U37

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 3U37 entry

There are 4 chains in PDB entry 3U37 (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	VAL 3	PHE 375
B	VAL 3	GLU 376
C	VAL 3	GLU 376
D	VAL 3	ASP 141

There are100 helices in PDB entry 3U37. Click on helix of interest for CSU analysis.
