Analysis of interatomic
Contacts of Structural
Units in PDB entry:
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, 327332).
This page provides analyses of
contacts formed by:
For analysis of ligandprotein contacts, use:
