'''Sulfotransferase''' (ST) are enzymes which catalyze the transfer of a sulfate group from a donor molecule to an acceptor alcohol or amine. The acceptors are hormones, neurotransmitters, drugs and xenobiotic compounds. The addition of a charged chemical moiety to the above carbon-rich water-insoluble molecules, make them more soluble and thus transportable in the circulatory system<ref>PMID:20136513</ref>. The various human STs are named SULT1, SULT2, SULT4 and differ in their tissue distribution and substrate specificities. The most common donor molecule is 3’-phosphoadenosine-5’-phosphosulfate (PAP). | '''Sulfotransferase''' (ST) are enzymes which catalyze the transfer of a sulfate group from a donor molecule to an acceptor alcohol or amine.
