Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of rhamnetin > isorhamnetin > quercetin > patuletin > kaempferol >ombuin > tamarixetin, but not quercertagetin, gossypetin or myricetin. O-sulfonation of position 3 of flavonol. May play a role in auxin transport. 3'-phosphoadenylyl sulfate + quercetin = adenosine 3',5'-bisphosphate + H(+) + quercetin 3-sulfate No requirement for divalent cations and insensitive to p-chloromercuribenzoate, iodoacetate, or iodoacetamide. Optimum pH is 6.0-8.5. Monomer. The N-terminus is blocked. Belongs to the sulfotransferase 1 family.
