General annotation (Comments)
| Function | Essential bifunctional enzyme that catalyzes both the N-deacetylation and the N-sulfation of glucosamine (GlcNAc) of the glycosaminoglycan in heparan sulfate. Modifies the GlcNAc-GlcA dissacharide repeating sugar backbone to make N-sulfated heparosan, a prerequisite substrate for later modifications in heparin biosynthesis. Plays a role in determining the extent and pattern of sulfation of heparan sulfate. Ref.4 Ref.5 Ref.6 |
| Catalytic activity | 3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine = adenosine 3',5'-bisphosphate + [heparan sulfate]-N-sulfoglucosamine. |
| Pathway | |
| Subunit structure | Monomer By similarity. |
| Subcellular location | Golgi apparatus membrane; Single-pass type II membrane protein By similarity. |
| Miscellaneous | The presence of 4 different heparan sulfate N-deacetylase/N-sulfotransferase enzymes in mammals, as well as differences in their enzyme activity suggest that some initiate heparan sulfate modification/sulfation reactions, whereas other later on fill in or extend already modified heparan sulfate sequences. |
| Sequence similarities | Belongs to the sulfotransferase 1 family. NDST subfamily. |
| Biophysicochemical properties | Kinetic parameters: KM=4.7 µM for K5 polysaccharide KM=0.76 µM for N-acetylated HS-II |
