Heparan-α-glucosaminide N-acetyltransferase (also called "acetyl-CoA:heparan-α-D-glucosaminide N-acetyltransferase" and "acetyl-CoA:alpha-glucosaminide N-acetyltransferase") is an enzyme that in humans is encoded by the HGSNAT gene.[1][2][3]

In enzymology, this enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. It is catalysed in the chemical reaction:

acetyl-CoA + heparan sulfate α-D-glucosaminide \rightleftharpoons CoA + heparan sulfate N-acetyl-α-D-glucosaminide

This enzyme participates in glycosaminoglycan degradation and glycan structures degradation. Mutations in the gene encoding this enzyme cause mucopolysaccharidosis IIIC.[2]
