The structure and bonding of the
sulfate ion
Sulfotransferases EC 2.8.2. are transferase enzymes that catalyze the transfer of a sulfate group from a donor molecule to an acceptor alcohol or amine.[1] The most common sulfate donor is 3'-phosphoadenosine-5'-phosphosulfate (PAPS). The destination alcohol or amine may be part of a protein, lipid, carbohydrate or steroid.[2]
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
- tyrosylprotein sulfotransferase: TPST1, TPST2
- uronyl-2-sulfotransferase: UST
