enzyme catalyzes the stoichiometric production of hydrogen sulfide and sulfite from thiosulfate. The most efficient coupling is obtained with a system containing cytochromes c3. The enzyme exhibits tetrathionate reductase activity. It does not show sulfite reductase activity |

| 1.8.2.5 | more |
the enzyme catalyzes the reductive dismutation of thiosulfate to sulfide and sulfite. The outer sulfur atom of thiosulfate is reduced to sulfide and the inner sulfur atom is released as sulfite |

| 1.8.2.5 | more |
with inner- and outer-labeled 35S-thiosulfate, the enzyme reduces only the outer sulfur atom to hydrogen sulfide. No substrates: sulfate, sulfite, tetrathionate, dithionate. No electron donors: reduced nicotinamide adenine dinucleotide, reduced nicotinamide adenine dinucleotide phosphate, reduced glutathione, or cysteine |
