- 3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine adenosine 3',5'-bisphosphate + [heparan sulfate]-glucosamine 3-sulfate
Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and heparan sulfate-glucosamine, whereas its two products are adenosine 3',5'-bisphosphate and heparan sulfate-glucosamine 3-sulfate.
This enzyme belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:[heparan sulfate]-glucosamine 3-sulfotransferase. This enzyme participates in heparan sulfate biosynthesis and glycan structures - biosynthesis 1.
