Glossary: 3'-phosphoadenylyl sulfate = PAPS
Other name(s): desulfoglucosinolate sulfotransferase (ambiguous); PAPS-desulfoglucosinolate sulfotransferase (ambiguous); 3'-phosphoadenosine-5'-phosphosulfate:desulfoglucosinolate sulfotransferase (ambiguous); 3'-phosphoadenylyl-sulfate:aromatic desulfoglucosinolate sulfotransferase
Systematic name: 3'-phosphoadenylyl-sulfate:aromatic desulfoglucosinolate sulfonotransferase
Comments: This enzyme, characterized from cruciferous plants, catalyses the last step in the biosynthesis of tryptophan- and phenylalanine-derived glucosinolates. cf. EC 2.8.2.38, aliphatic desulfoglucosinolate sulfotransferase.
