Outline of Final Research Achievements |
3-Mercaptopyruvate sulfurtransferase (3MST) produces hydrogen sulfide (H2S) and polyfulfides (H2Sn). H2Sn S-sulfurate cysteine residues of the target proteins, while H2S S-sulfurates the oxidized cysteie residues such as Cys-SOH to generate Cys-SSH. It correlate well with the increase in the amount of bound sulfane sulfur. We elucidated that 3MST increases S-sulfurated proteins, namely the levels of bound sulfane sulfur by using 3MST knockout mice. We also showed that the two cysteine residues of TRPA1 channels are S-sulfurated to activate the channels.
