Pathways involved in enzymatic biogenesis of H2S. The transsulfuration pathway consisting of the enzymes cystathionine β-synthase (CBS) and Cystathionine γ-lyase (CSE) is the major pathway for biological H2S production. In addition to this 3-mercaptopyruvate sulfurtransferase/cysteine aminotransferase (3-MST/CAT) pathway also contribute significantly to the production of H2S.
