Recombinant Human SULT1B1 Protein (His Tag)(Active)

Sulfotransferase family cytosolic 1B member 1; also known as Sulfotransferase 1B1; Sulfotransferase 1B2; Thyroid hormone sulfotransferase; SULT1B1 and ST1B2; is a cytoplasm protein which belongs to the sulfotransferase 1 family. Sulfotransferase enzymes catalyze the sulfate conjugation of many hormones; neurotransmitters; drugs; and xenobiotic compounds. These cytosolic enzymes are different in their tissue distributions and substrate specificities. SULT1B1 is highly expressed in the liver; peripheral blood leukocytes; colon (mucosal lining); small intestine (jejunum) and spleen. A lesser expression of SULT1B1 was observed in the lung; placenta and thymus. SULT1B1 catalyzes the sulfate conjugation of many hormones; neurotransmitters; drugs and xenobiotic compounds. Sulfonation increases the water solubility of most compounds; and therefore their renal excretion; but it can also result in bioactivation to form active metabolites. SULT1B1 sulfates dopamine; small phenols such as 1-naphthol and p-nitrophenol and thyroid hormones; including 3;3′-diiodothyronine; triidothyronine; reverse triiodothyronine and thyroxine.
