Application
Adenosine-5′-triphosphate sulfurylase (ATP sulfurylase) may be used to study sulfur metabolism and hydrogen sulfide biosynthesis. ATP sulfurylase is also used in pyrosequencing. The enzyme has been used along with luciferase in a bioluminescent assay for inorganic sulfate quantitation in freshwater. Inorganic sulfate is converted, by ATP sulfurylase, into adenosine-5′-phosphosulfate and inorganic pyrophosphate, with consumption of ATP. The remaining ATP is used as a co-factor in the reaction catalyzed by firefly luciferase, generating photons of visible light as a co-product. The light output is inversely proportional to the content of inorganic sulfate.
Biochem/physiol Actions
Adenosine-5′-triphosphate sulfurylase catalyzes the first intracellular reaction of sulfate assimilation, which forms adenosine-5′-phosphosulfate (APS) from inorganic sulfate and ATP. It is involved in sulfate activation and the biosynthesis pathway of sulfur-containing amino acids. The expression of ATP sulfurylase is dependent on the formation of the MET4-MET28-MET31 and MET4-MET28-MET32 complexes on its 5′ upstream region .
Physical form
Contains citrate buffer salts
Other Notes
One unit will produce 1.0 μmole of ATP from APS and inorganic pyrophosphate per min at pH 8.0 at 30°C.

In pyrosequencing chemistry, four cascade enzymatic reactions with the catalysis of polymerase, adenosine triphosphate (ATP) sulfurylase, luciferase, and apyrase are employed. The sensitivity of pyrosequencing mainly depends on the concentration of luciferase which catalyzes a photoemission reaction. However, the side-reaction

Sulfur is a macronutrient that is necessary for plant growth and development. Sulfate, a major source of sulfur, is taken up by plant roots and transported into various tissues for assimilation. During sulfate limitation, expression of miR395 is significantly up-regulated.
