Báo cáo khoa học: Three enzymatic activities catalyze the oxidation of sulfide to thiosulfate in mammalian and invertebrate mitochondria

Hydrogen sulfide is a potent toxin of aerobic respiration, but also has physiological functions as a signalling molecule and as a substrate for ATP production. A mitochondrial pathway catalyzing sulfide oxidation to thio-sulfate in three consecutive reactions has been identified in rat liver as well as in the body-wall tissue of the lugworm,Arenicola marina.
