Hello! I am searching for a database/tool/anything that is able to tell me if a posttransational modification of a protein (in my case s-glutathionylation) inhibits or not a protein. I have a proteomic analysis from which I see which proteins are s-glutathionylated and which are not. I need to see which pathways end up being altered as a consequence of this s-glutathionylation. Can anyone help me with this please? R/python packages are welcome too. Thanks a lot!
