Glycoprotein endo-alpha-1,2-mannosidase

Glycoprotein endo-α-1,2-mannosidase (, glucosylmannosidase, endo-α- D -mannosidase, endo-α-mannosidase, endomannosidase, glucosyl mannosidase) is an enzyme with systematic name glycoprotein glucosylmannohydrolase. It catalyses the hydrolysis of the terminal α- D -glucosyl-(1,3)- D -mannosyl unit from the GlcMan9(GlcNAc)2 oligosaccharide component of the glycoprotein produced in the Golgi membrane.

This protein is involved in the synthesis of glycoproteins.
