Bifunctional heparan sulfate N-deacetylase/N-sulfotransferase 1

Gene

NDST1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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 (PubMed:10758005, PubMed:12634318). 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 (PubMed:10758005, PubMed:12634318). Required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413).3 Publications

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.

Catalytic activityi

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

    Involvement in diseasei

    Mental retardation, autosomal recessive 46 (MRT46)1 Publication
    The disease is caused by mutations affecting the gene represented in this entry.
    Disease descriptionA disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT46 manifestations include delayed psychomotor development apparent from infancy or early childhood, delayed or absent expressive speech, hypotonia, and therapy-responsive seizures in some patients. Behavioral abnormalities are variable and include aggression, self-injurious behavior, and sleep disturbances.
