ID 1.8.5.5 DE thiosulfate reductase (quinone). CA a quinone + 2 H(+) + hydrogen sulfide + sulfite = a quinol + thiosulfate. CC -!- The enzyme, characterized from the bacterium Salmonella enterica, CC is similar to EC 1.17.5.3. CC -!- The reaction occurs in vivo in the direction of thiosulfate CC disproportionation, which is highly endergonic. CC -!- It is driven by the proton motive force that occurs across the CC cytoplasmic membrane. DR P37600, PHSA_SALTY ; //
