The Modus Operandi of Hydrogen Sulfide(H₂S)-Dependent Protein Persulfidation in Higher Plants

Antioxidants, 2021
Protein persulfidation is a post-translational modification (PTM) mediated by hydrogen sulfide (H2S), which affects the thiol group of cysteine residues from target proteins and can have a positive, negative or zero impact on protein function.
