General Information | Comment | Organism |
---|---|---|
physiological function | thiosulfate reductase activity depends on the proton motive force across the cytoplasmic membrane. The proton motive force drives endergonic electron flow within the enzyme by a reverse loop mechanism. Thiosulfate reductase is able to catalyze the combined oxidation of sulfide and sulfite to thiosulfate in a reverse of the physiological reaction. In contrast to the forward reaction, the exergonic thiosulfate-forming reaction is independent of the proton motive force | Salmonella enterica |
