Hydrogen sulfide: An endogenous regulator of the …

Hydrogen sulfide (H 2 S) is now recognized as an endogenous signaling gasotransmitter in mammals. It is produced by mammalian cells and tissues by various enzymes - predominantly cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST) - but part of the H 2 S is produced by the intestinal microbiota (colonic H 2 S-producing bacteria).
