Protein
Cytosolic sulfotransferase 5
Organism
Arabidopsis thaliana
Function
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to specifically catalyze the sulfate conjugation of flavones and flavonols. Strictly specific for the position 7. Substrate preference is kaempferol 3-sulfate > isorhamnetin > kaempferol.
Similarity
Belongs to the sulfotransferase 1 family.
