Accepted name: aromatic desulfoglucosinolate sulfotransferase

Reaction: (1) 3'-phosphoadenylyl sulfate + desulfoglucotropeolin = adenosine 3',5'-bisphosphate + glucotropeolin
(2) 3'-phosphoadenylyl sulfate + indolylmethyl-desulfoglucosinolate = adenosine 3',5'-bisphosphate + glucobrassicin

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, aliphatic desulfoglucosinolate sulfotransferase.
