Quercetin-3,3'-bissulfate 7-sulfotransferase (EC 2.8.2.28) 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 3,3'-bissulfate to quercetin 3,3',7-trisulfate. This is part of a sequence of similar reactions which sequentially add sulfate groups to quercetin.[1]
This enzyme is a transferase, specifically a sulfotransferase, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:quercetin-3,3'-bissulfate 7-sulfotransferase. Other names in common use include flavonol 7-sulfotransferase, 7-sulfotransferase, and PAPS:flavonol 3,3'/3,4'-disulfate 7-sulfotransferase.[2]
