Flavonol 3-sulfotransferase

In enzymology, a flavonol 3-sulfotransferase is an enzyme that catalyzes the chemical reaction


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

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

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-sulfotransferase.
