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.
Abbr
ATP Sulfurylase, Recombinant (S. cerevisiae)
Product Overview
Adenosine 5’-Triphosphate Sulfurylase Yeast Recombinant produced in E. coli is a non-glycosylated, polypeptide chain containing 511 amino acids and having a Mw of 57.7 kDa. Adenosine 5’-Triphosphate Sulfurylase Yeast Recombinant catalyzes the activation of sulfate by transferring sulfate to the adenine monophosphate moiety of ATP to form adenosine 5’-phosphosulfate (APS) and pyrophosphate (PPi). The reaction is reversible: ATP is formed from APS and PPi. Adenosine 5’-Triphosphate Sulfurylase is purified by proprietary chromatographic techniques.
Unit Definition
One unit is the amount of enzyme which incorporates 1 pmol AMP into acid-insoluble material at 37°C in 1 minute.
