Due to the cysteine residues of GSH, it can be readily oxidized to glutathione disulfide (GSSG) by electrophilic species directly (e.g., combine with NO to form less reactive S-nitrosoglutathione), or indirectly through enzymatic reactions (e.g., reduce hydrogen peroxide to water by glutathione peroxidase)

You dont have to know what your protein of interest interacts with beforehand

To test this hypothesis, we first purified Pmc4 proteins expressed in Escherichia coli and observed that Pmc4 formed droplets when exposed to PEG concentrations exceeding 5%, implying that Pmc4 may undergo droplet formation (Supplementary Fig
