Analysis of interatomic Contacts of Structural Units in PDB entry:
6ACK

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 6ACK entry

There are 4 chains in PDB entry 6ACK (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue

B	ARG 18	VAL 1119
C	ARG 18	VAL 1119
D	SER 19	ASP 615

There are 73 helices in PDB entry 6ACK. Click on helix of interest for CSU analysis.
