Analysis of interatomic Contacts of Structural Units in PDB entry:
7T4V

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 7T4V 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.
