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 disaccharide 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. Compared to other NDST enzymes, its presence is absolutely required. Participates in biosynthesis of heparan sulfate that can ultimately serve as L-selectin ligands, thereby playing a role in inflammatory response. Ref.6 Ref.7
Catalytic activity	3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine = adenosine 3',5'-bisphosphate + [heparan sulfate]-N-sulfoglucosamine.
Pathway	Glycan metabolism; heparan sulfate biosynthesis. Glycan metabolism; heparin biosynthesis.
Subunit structure	Monomer.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein Ref.2.
Tissue specificity	Widely expressed. Expression is most abundant in heart, liver and pancreas.
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=13.3 µM for K5 polysaccharide Ref.7 KM=0.35 µM for N-acetylated HS-II
