Tetrathionate hydrolase from the acidophilic microorganisms [PDF]

open access: yesFrontiers in Microbiology
Tetrathionate hydrolase (TTH) is a unique enzyme found in acidophilic sulfur-oxidizing microorganisms, such as bacteria and archaea. This enzyme catalyzes the hydrolysis of tetrathionate to thiosulfate, elemental sulfur, and sulfate.
