IUBMB Enzyme Nomenclature


Accepted name: N-acetylglucosamine-1-phosphodiester α-N-acetylglucosaminidase

Reaction: glycoprotein N-acetyl-D-glucosaminyl-phospho-D-mannose + H2O = N-acetyl-D-glucosamine + glycoprotein phospho-D-mannose

Other name(s): α-N-acetylglucosaminyl phosphodiesterase; lysosomal α-N-acetylglucosaminidase; phosphodiester glycosidase; α-N-acetyl-D-glucosamine-1-phosphodiester N-acetylglucosaminidase; 2-acetamido-2-deoxy-α-D-glucose 1-phosphodiester acetamidodeoxyglucohydrolase

Systematic name: glycoprotein-N-acetyl-D-glucosaminyl-phospho-D-mannose N-acetyl-D-glucosaminylphosphohydrolase

Comments: Acts on a variety of compounds in which N-acetyl-D-glucosamine is α-linked to a phosphate group, including the biosynthetic intermediates of the high mannose oligosaccharide components of some lysosomal enzymes and the products of EC UDP-N-acetylglucosamine—lysosomal-enzyme N-acetylglucosaminephosphotransferase.
