Tetrathionate hydrolase (4THase) plays an important role in dissimilatory sulfur metabolism in the acidophilic chemolithoautotrophic iron- and sulfur-oxidizing bacterium Acidithiobacillus ferrooxidans. We have already identified the gene encoding 4THase (Af-tth) in this bacterium. The heterologous expression of Af-tth in Escherichia coli resulted in the(More)
Tetrathionate hydrolase (4THase) from the iron- and sulfur-oxidizing bacterium Acidithiobacillus ferrooxidans catalyses the disproportionate hydrolysis of tetrathionate to elemental sulfur, thiosulfate and sulfate. The gene encoding 4THase (Af-tth) was expressed as inclusion bodies in recombinant Escherichia coli. Recombinant Af-Tth was activated by(More)
