Abstract Nitric oxide (NO) and hydrogen sulfide (H2S) are two molecules that share signaling properties in plant and
animal cells. NO and H2S originate two families of derived molecules designated reactive nitrogen and sulfur species (RNS
and RSS, respectively). These molecules are responsible for certain protein regulatory processes through posttranslational
modifications (PTMs), being the most remarkable S-nitrosation and persulfidation, which affect the thiol group of
cysteine residues. NO and H2S can also exert regulatory functions due to their interaction through the iron present in
proteins that contain heme groups or iron-sulfur clusters, as reported mainly in animal cells. More >
