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


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).
For CSU analysis of other PDB entry

This page provides analyses of contacts formed by:
For analysis of ligand-protein contacts, use: 3D structure can be seen in additional window with STING software for 3OCB entry


Note, this PDB entry contains modified residue(s) PHOSPHOTHREONINE (TPO) . This residue is treated as heterogroup (ligand) both in the PDB entry and in LPC/CSU analysis.
