Name
thiosulfate---thiol sulfurtransferase;
glutathione-dependent thiosulfate reductase;
sulfane reductase;
sulfane sulfurtransferase
Class
Transferases;
Transferring sulfur-containing groups;

Sysname
thiosulfate:thiol sulfurtransferase
Reaction(IUBMB)
thiosulfate + 2 glutathione = sulfite + glutathione disulfide + sulfide [RN:R01875]
Reaction(KEGG)
R01875
Substrate
thiosulfate [CPD:C00320];
glutathione [CPD:C00051]
Product
sulfite [CPD:C00094];
glutathione disulfide [CPD:C00127];
sulfide [CPD:C00283]
Comment
The primary product is glutathione hydrodisulfide, which reacts with glutathione to give glutathione disulfide and sulfide. L-Cysteine can also act as acceptor.
