In biochemistry, sulfotransferases (SULTs) are transferase enzymes that catalyze the transfer of a sulfo group (R−SO3) from a donor molecule to an acceptor alcohol (R−OH) or amine (R−NH2).[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]
