Reaction: 2 thiosulfate + 6-decylubiquinone = tetrathionate + 6-decylubiquinol
Other name(s): thiosulfate:quinone oxidoreductase; thiosulphate:quinone oxidoreductase; thiosulfate oxidoreductase, tetrathionate-forming; TQO
Systematic name: thiosulfate:6-decylubiquinone oxidoreductase
Comments: The reaction can also proceed with ferricyanide as the electron acceptor, but more slowly. Unlike EC 1.8.2.2, thiosulfate dehydrogenase, this enzyme cannot utilize cytochrome c as an acceptor.
