ID 1.8.5.2 DE Thiosulfate dehydrogenase (quinone). AN Thiosulfate oxidoreductase, tetrathionate-forming. AN Thiosulfate:quinone oxidoreductase. AN TQO. CA 2 thiosulfate + 2 6-decylubiquinone = tetrathionate + 2 6-decylubiquinol. CC -!- The reaction can also proceed with ferricyanide as the electron CC acceptor, but more slowly. CC -!- Unlike EC 1.8.2.2, this enzyme cannot utilize cytochrome c as an CC acceptor. //
