Desulfoglucosinolate sulfotransferase (EC 2.8.2.24) is an enzyme that catalyzes related chemical reactions which add a sulfate group in the final step of the biosynthesis of tryptophan- and phenylalanine-derived glucosinolates:

a glucosinolate +
 

It uses the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) and gives adenosine 3',5'-bisphosphate as a byproduct. For example, the enzyme characterised from Brassica converts desulfoglucotropaeolin to glucotropaeolin:[1]

Related enzymes act to give other glucosinolates.[2][3][4]

This enzyme is a transferase, specifically a sulfotransferase, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:desulfoglucosinolate sulfotransferase. Other names in common use include PAPS-desulfoglucosinolate sulfotransferase, 3'-phosphoadenosine-5'-phosphosulfate:desulfoglucosinolate, and sulfotransferase.[5]
