Quercetin-3-sulfate 4'-sulfotransferase

Template:Short description Template:Infobox enzyme In enzymology, a quercetin-3-sulfate 4'-sulfotransferase (Template:EC number) is an enzyme that catalyzes the chemical reaction

3'-phosphoadenylyl sulfate + quercetin 3-sulfate $\rightleftharpoons$ adenosine 3',5'-bisphosphate + quercetin 3,4'-bissulfate

Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and quercetin 3-sulfate, whereas its two products are adenosine 3',5'-bisphosphate and quercetin 3,4'-bissulfate.

This enzyme belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:quercetin-3-sulfate 4'-sulfotransferase. Other names in common use include flavonol 4'-sulfotransferase, and PAPS:flavonol 3-sulfate 4'-sulfotransferase.
