Analysis of interatomic Contacts of Structural Units in PDB entry:
4LF2


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 4LF2 entry

There are 12 chains in PDB entry 4LF2 (CSU analysis of residue contacts immediately below table)
