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. 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.

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 By similarity.

Subcellular location

Golgi apparatus membrane; Single-pass type II membrane protein Ref.4.

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=144 µM for K5 polysaccharide (for deacetylase activity) Ref.3

KM=160 µM for K5 polysaccharide (for sulfotransferase activity)

Vmax=40 µmol/min/mg enzyme with K5 polysaccharide as substrate (for deacetylase activity)

Vmax=2104 µmol/min/mg enzyme with K5 polysaccharide as substrate (for sulfotransferase activity)
