In enzymology, a [heparan sulfate]-glucosamine 3-sulfotransferase 2 (EC 126.96.36.199) is an enzyme that catalyzes the chemical reaction3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine
Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and heparan sulfate-glucosamine, whereas its two products are adenine 3',5'-bis-phosphate and heparin sulfate-glucosamine 3-sulfate.
This enzyme belongs to the family of transferences, specifically the transformer, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphorylation-sulfate:[heparin sulfate]-glucose 3-nontransferable. Other names in common use include glucose 3-O-nontransferable, heparin sulfate D-glucose 3-O-nontransferable, and formalism/isomerism 2 (3-OAT-2, HST). This enzyme participates in heparin sulfate biosynthesis and glycogen structures - biosynthesis 1.
