Native Saccharomyces cerevisiae Adenosine-5'-triphosphate Sulfurylase

Cat No.
NATE-0090
Description
In enzymology, a sulfate adenylyltransferase (EC 2.7.7.4) is an enzyme that catalyzes the chemical reaction:ATP + sulfate↔ diphosphate + adenylyl sulfate. Thus, the two substRates of this enzyme are ATP and sulfate, whereas its two products are diphosphate and adenylyl sulfate. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). This enzyme participates in 3 metabolic pathways:purine metabolism, selenoamino acid metabolism, and sulfur metabolism.

ATP-sulfurylase, Native (Saccharomyces cerevisiae)
Alias
ATP-sulfurylase; sulfurylase

Applications
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.
