UniProtKB description: Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan (PubMed:15060080, PubMed:9346953). Catalyzes the rate limiting step in the biosynthesis of heparan sulfate (HSact) (PubMed:15060080, PubMed:9346953). This modification is a crucial step in the biosynthesis of anticoagulant heparan sulfate as it completes the structure of the antithrombin pentasaccharide binding site (PubMed:15060080, PubMed:9346953).
