The Capacity to Produce Hydrogen Sulfide (H2S) via Cysteine Degradation Is Ubiquitous in the Human Gut Microbiome

Abstract excerpt

As one of the three mammalian gasotransmitters, hydrogen sulfide (H 2 S) plays a major role in maintaining physiological homeostasis. Endogenously produced H 2 S plays numerous beneficial roles including mediating vasodilation and conferring neuroprotection. Due to its high membrane permeability, exogenously produced H 2 S originating from the gut microbiota can also influence human physiology and is implicated...
