text: user7371: Does the protein structure shown in the JSmol link have any Sulfur Dioxide molecules?
  
  In the picture, the Sulfur element is yellow and Oxygen is red (see here)

  Link to mmcif file (I have the VS Code plugin installed):
  https://files.rcsb.org/view/1P9S.cif
  
  user7371: The answer, as provided in the comments by gilleain is No. The commenter wanted to know why I asked this. The reason is I heard sulfur dioxide as silent speech when thinking about antibodies that’s why I asked.
  I searched the file https://files.rcsb.org/view/1P9S.cif for the SO2 molecule and didn't find it. I got confirmation in the comments of the question.
  Would anyone be interested in an app that takes a .cif file of a molecule and allows you to search the file for any type of element or molecule in it? Would that help anyone with their research?
