IUBMB Enzyme Nomenclature


Accepted name: [heparan sulfate]-glucosamine N-sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine = adenosine 3',5'-bisphosphate + [heparan sulfate]-N-sulfoglucosamine

Glossary: 3'-phosphoadenylyl sulfate = PAPS

Other names: heparin N-sulfotransferase; 3'-phosphoadenylylsulfate:N-desulfoheparin sulfotransferase; PAPS:N-desulfoheparin sulfotransferase; PAPS:DSH sulfotransferase; N-HSST; N-heparan sulfate sulfotransferase; heparan sulfate N-deacetylase/N-sulfotransferase; heparan sulfate 2-N-sulfotransferase; heparan sulfate N-sulfotransferase; heparan sulfate sulfotransferase; N-desulfoheparin sulfotransferase; desulfoheparin sulfotransferase; 3'-phosphoadenylyl-sulfate:N-desulfoheparin N-sulfotransferase; heparitin sulfotransferase; 3'-phosphoadenylyl-sulfate:heparitin N-sulfotransferase; 3'-phosphoadenylyl-sulfate:[heparan sulfate]-glucosamine N-sulfotransferase

Systematic name: 3'-phosphoadenylyl-sulfate:[heparan sulfate]-glucosamine N-sulfonotransferase

Comments: The enzyme also catalyses the sulfation of chondroitin 4-sulfate and dermatan sulfate, but to a much more limited extent.
