(heparan sulfate)-glucosamine 3-sulfotransferase 3

In enzymology, a [heparan sulfate]-glucosamine 3-sulfotransferase 3 (EC 2.8.2.30) is an enzyme that catalyzes the chemical reaction

3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine ${\displaystyle \rightleftharpoons }$ 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-.

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 .
