  • Title: Amine N-sulfotransferase.
    Author: Ramaswamy SG, Jakoby WB.
    Journal: J Biol Chem; 1987 Jul 25; 262(21):10039-43. PubMed ID: 3475273.
    Abstract:
    A highly purified amine N-sulfotransferase has been isolated from guinea pig liver that catalyzes sulfuryl group transfer from 3'-phosphoadenosine 5'-phosphosulfate to one of a large number of either primary or secondary amines forming the appropriate sulfamate and adenosine 3',5'-bisphosphate. Amines as different as aniline, 2-naphthylamine, octylamine, 1,2,3,4-tetrahydroisoquinoline and 1,2,3,4-tetrahydroisoquinoline, desmethylimipramine, and cyclohexylamine serve as acceptors; the product of the last of these substrates is the sugar-substitute cyclamate. Amine N-sulfotransferase activity is dependent on the presence of an unprotonated amino group. The purified enzyme preparation also has O-sulfotransferase activities, suggesting that transfer to oxygen could represent an intrinsic function of the N-sulfotransferase.
