Figure 1 Schematic presentation of pathways for hydrogen sulfide synthesis from L- and D-cysteine via the enzymes cystathionine-γ-lyase, cystathionine-β-synthetase, cysteine amino transferase, D-amino acid oxidase and 3-mercaptopyruvate sulfurtransferase. H2S: Hydrogen sulfide; CSE: Cystathionine-γ-lyase; CBS: Cystathionine-β-synthetase; CAT: Cysteine amino transferase; DAO: D-amino acidoxidase; 3MTS: 3-mercaptopyruvate sulfurtransferase.
