In enzymology a keratan sulfotransferase (EC 2.8.2.21) is an enzyme that catalyzes the chemical reaction3′-phosphoadenylyl sulfate + keratan adenosine 3’5′-bisphosphate + keratan 6′-sulfateThus the two substrates of this enzyme are 3′-phosphoadenylyl sulfate and keratan whereas its two products are adenosine 3’5′-bisphosphate and keratan 6′-sulfate.This enzyme belongs to the family of transferases specifically the sulfotransferases which transfer sulfur-containing groups.
