Glycoprotein endo-α-1,2-mannosidase (EC 3.2.1.130, glucosylmannosidase, endo-α-D-mannosidase, endo-α-mannosidase, endomannosidase, glucosyl mannosidase) is an enzyme with systematic name glycoprotein glucosylmannohydrolase.[1][2] 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.
