Analysis of interatomic Contacts of Structural Units in PDB entry:
4Q9A


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:
For analysis of ligand-protein contacts, use: 3D structure can be seen in additional window with STING software for 4Q9A entry


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