2.8.2.24

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 2.8.2.38, aliphatic desulfoglucosinolate sulfotransferase.
