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

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 1MPX entry

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

Chain ID	Initial residue	Terminal residue

B	THR 24	ARG 637
C	THR 24	ARG 637
D	THR 24	ARG 637

There are100 helices in PDB entry 1MPX. Click on helix of interest for CSU analysis.
