Sulfotransferase
Sulfotransferases (SULTs) are transferase enzymes that catalyze the transfer of a sulfo group from a donor molecule to an acceptor alcohol or amine.[1] 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.[2]

gollark: Wait, there might be secret data but it's hidden.
gollark: Hmm, so there is NOT secret data in the non-visible corner bits.
