  Hydrogen sulfide is produced from l-cysteine by the action of both cystathionine γ-lyase (CSE) and cystathionine β-synthase (CBS) and increasingly has been found to play a profound regulatory role in a range of physiological processes. Mounting evidence suggests that upregulation of hydrogen sulfide biosynthesis occurs in several disease states, including rheumatoid arthritis, hypertension, ischemic
