In [[enzymology]], a '''quercetin-3,3'-bissulfate 7-sulfotransferase''' ({{EC number|2.8.2.28}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:3'-phosphoadenylyl sulfate + quercetin 3,3'-bissulfate <math>\rightleftharpoons</math> adenosine 3',5'-bisphosphate + quercetin 3,7,3'-trissulfate

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[3'-phosphoadenylyl sulfate]] and [[quercetin 3,3'-bissulfate]], whereas its two [[product (chemistry)|products]] are [[adenosine 3',5'-bisphosphate]] and [[quercetin 3,7,3'-trissulfate]].

This enzyme belongs to the family of [[transferase]]s, specifically the sulfotransferases, 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'''.
