Analysis of interatomic Contacts of Structural Units in PDB entry:
1YNA

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 1YNA entry

There is 1 chain in PDB entry 1YNA (CSU analysis of residue contacts immediately below table)

Chain ID	Initial residue	Terminal residue
A	THR 2	GLY 194

There is 1 helix in PDB entry 1YNA. Click on helix number for CSU analysis.

Helix number	Helix ID	Chain ID	Initial residue	Terminal residue	Helix class
Helix 1	1	A	153	162	Right-handed alpha

There are 2 sheets in PDB entry 1YNA. Click on sheet of interest to get list of strands forming it: A, B,
