Disulfide Bond Analysis
Introduction of disulfide bonds into proteins appears to be an important mechanism by which they have evolved and are evolving.
At the bottom of this page you will find our software for analysing disulfide bonds. Any structure from the PDB can be analysed by entering its PDB identifier. Alternatively, custom PDB files may be uploaded. The analysis can be downloaded as an Excel 97-2003 spreadsheet.
The analysis of the disulfides from all of the PDB, both X-ray and NMR structures (about 60,000 bonds currently), can be directly downloaded. This analysis will be updated every month.

This web service also provides a remote API for accessing the analysis software. An example of how to do this is below:
where the PDB ID 1cdj maybe replace with any PDB ID in the RCSB Protein Data Bank.
