Sulfotransferase

Sulfotransferases EC 2.8.2.- are transferase enzymes that catalyze the transfer of a sulfo group from a donor molecule to an acceptor alcohol or amine. The most common sulfo group donor is 3'-phosphoadenosine-5'-phosphosulfate (PAPS). In the case of alcohol as acceptor, the product is a sulfate (R-OSO3−), whereas an amine leads to a sulfamate (R-NH-SO3−). Both reactive groups for a sulfonation via sulfotransferases may be part of a protein, lipid, carbohydrate or steroid.

Examples

The following are examples of sulfotransferases:

  • carbohydrate sulfotransferase: CHST1, CHST2, CHST3, CHST4, CHST5, CHST6, CHST7, CHST8, CHST9, CHST10, CHST11, CHST12, CHST13, CHST14
  • galactose-3-O-sulfotransferase: GAL3ST1, GAL3ST2, GAL3ST3, GAL3ST4
  • heparan sulfate 2-O-sulfotransferase: HS2ST1,
  • heparan sulfate 3-O-sulfotransferase: HS3ST1, HS3ST2, HS3ST3A1, HS3ST3A2, HS3ST3B1, HS3ST3B2, HS3ST4, HS3ST5, HS3ST6
  • heparan sulfate 6-O-sulfotransferase: HS6ST1, HS6ST2, HS6ST3
  • N-deacetylase/N-sulfotransferase: NDST1, NDST2, NDST3, NDST4
