EC 2.8.2.28     
Accepted name: quercetin-3,3′-bissulfate 7-sulfotransferase
Reaction: 3′-phosphoadenylyl sulfate + quercetin 3,3′-bissulfate = adenosine 3′,5′-bisphosphate + quercetin 3,7,3′-trissulfate
Glossary: 3′-phosphoadenylyl sulfate = PAPS
Other name(s): flavonol 7-sulfotransferase; 7-sulfotransferase; PAPS:flavonol 3,3′/3,4′-disulfate 7-sulfotransferase; 3′-phosphoadenylyl-sulfate:quercetin-3,3′-bissulfate 7-sulfotransferase
Systematic name: 3′-phosphoadenylyl-sulfate:quercetin-3,3′-bissulfate 7-sulfonotransferase
Comments: Quercetin 3,4′-bissulfate can also act as acceptor.
