Urechis unicinctus the enzyme is induced by sulfide in the hindgut, about 2fold after 72 h, but not in the midgut up

General Information

General Information Comment Organism
physiological function the worm living in coastal burrows is periodically exposed to the sulfide, a mixture of H2S, HS- and S2+, during low tide. Mitochondrial sulfide oxidation is an important strategy that allows organisms to avoid injury from sulfide exposure, and sulfur dioxygenase (SDO) plays an essential role. The hindgut of the worm plays more important role than the midgut in sulfide tolerance Urechis unicinctus
