Quercetin-3-sulfate 4'-sulfotransferase (EC 2.8.2.27) is an enzyme that catalyzes the chemical reaction
It uses the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) to transfer a sulfate group and gives adenosine 3',5'-bisphosphate as a byproduct. The enzyme characterised from Flaveria chlorifolia converts quercetin 3-O-sulfate to quercetin 3,4'-bissulfate. The starting material is produced from quercetin by a similar reaction catalysed by the enzyme flavonol 3-sulfotransferase.[1]
This enzyme is transferase, specifically a sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:quercetin-3-sulfate 3'-sulfotransferase. Other names in common use include flavonol 3'-sulfotransferase, 3'-Sulfotransferase, and PAPS:flavonol 3-sulfate 3'-sulfotransferase.[2]
