Analysis of interatomic Contacts of Structural Units in PDB entry:
7FEM

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 7FEM entry

There are 4 chains in PDB entry 7FEM (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue

B	ALA 27	SER 1147
C	ALA 27	SER 1147
D	SER 19	TYR 613

There are 91 helices in PDB entry 7FEM. Click on helix of interest for CSU analysis.
