EC 2.8.1.3

Accepted name: thiosulfate—thiol sulfurtransferase

Reaction: thiosulfate + 2 glutathione = sulfite + glutathione disulfide + sulfide

Other name(s): glutathione-dependent thiosulfate reductase; sulfane reductase; sulfane sulfurtransferase

Systematic name: thiosulfate:thiol sulfurtransferase

Comments: The primary product is glutathione hydrodisulfide, which reacts with glutathione to give glutathione disulfide and sulfide. L-Cysteine can also act as acceptor.
