3MST produces redox regulators Cys-SSH and GSSH as well as signaling molecules H2S and H2Sn

3-Mercaptopyruvate sulfurtransferase (3MST) together with cysteine aminotransferase (CAT) produces hydrogen sulfide (H2S), a well-known toxic gas, from L-cysteine. 3MST also produces H2S from D-cysteine in concert with D-amino acid oxidase (DAO). Cystathionine β–synthase (CBS) and cystathionine γ–lyase
