N acetylglucosamine 1 phosphodiester alpha N acetylglucosaminidase

In enzymology, a N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase (EC 3.1.4.45) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are glycoprotein N-acetyl-D-glucosaminyl-phospho-D-mannose and H₂O, whereas its two products are N-acetyl-D-glucosamine and glycoprotein phospho-D-mannose.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric diester bonds. The systematic name of this enzyme class is glycoprotein-N-acetyl-D-glucosaminyl-phospho-D-mannose N-acetyl-D-glucosaminylphosphohydrolase. Other names in common use include alpha-N-acetylglucosaminyl phosphodiesterase, lysosomal alpha-N-acetylglucosaminidase, phosphodiester glycosidase, alpha-N-acetyl-D-glucosamine-1-phosphodiester, N-acetylglucosaminidase, 2-acetamido-2-deoxy-alpha-D-glucose 1-phosphodiester, and acetamidodeoxyglucohydrolase.
