The enzyme N-acetylglucosamine-1-phosphodiester α-N-acetylglucosaminidase catalyzes the reaction glycoprotein N-acetyl-D-glucosaminyl-phospho-D-mannose + H2O ⇌ {\displaystyle \rightleftharpoons } N-acetyl-D-glucosamine + glycoprotein phospho-D-mannoseThis enzyme belongs to the family of hydrolases, specifically those acting on phosphoric diester bonds.
