3.2.1.207 Glc2Man9GlcNAc2 (G2M9)-protein + H2O glucosidase II plays a key role in glycoprotein processing in the endoplasmic reticulum. This enzyme trims two alpha-1,3-linked glucose residues, Glcalpha1,3Glc (cleavage 1) and Glcalpha1,3Man (cleavage 2) from high-mannose type Glc2Man9GlcNAc2 (G2M9)-proteins. A crowded milieu that contains bovine serum albumin greatly enhances the second trimming step (cleavage 2), which deglucosylates Glc1Man9GlcNAc2, but not the first trimming step (cleavage 1), which removes the terminal glucose residue from Glc2Man9GlcNAc2 3.2.1.207 Glc2Man9GlcNAc2 + H2O - 3.2.1.207 Glc2Man9GlcNAc2 + H2O involved in the Calnexin Cycle 3.2.1.207 Glc2Man9GlcNAc2 + H2O processing of asparagine-linked oligosaccharides 3.2.1.207 Glc2Man9GlcNAc2 + H2O removal of glucose residues allows newly synthesized glycoproteins to interact with calnexin and calreticulin, that are part of the chaperone mechanism 3.2.1.207 Glc2Man9GlcNAc2 + H2O i.e. G1M9 3.2.1.207 GlcMan9GlcNAc2 + H2O - 3.2.1.207 GlcMan9GlcNAc2 + H2O G2M9 3.2.1.207 additional information Catalyzes the hydrolysis of the inner two alpha-1,3-linked glucose residues present in all N-linked immature oligosaccharides, associates with and glycosylates the protein CD45, possible role in CD45 regulation 3.2.1.207 additional information involved in early glycoprotein biogenesis, catalyzes the hydrolysis of two alpha-1,3-linked glucose residues present on all Asn-linked precursor oligosaccharides 3.2.1.207 additional information deletion of the glucosidase II gene in Trypanosoma brucei reveals novel N-glycosylation mechanisms in the biosynthesis of variant surface glycoprotein 3.2.1.207 additional information endoplasmic reticulum glucosidase II is required for pathogenicity of Ustilago maydis 3.2.1.207 additional information the enzyme is involved in the processing of protein-linked N-glycans in the endoplasmic reticulum of filamentous fungi 3.2.1.207 additional information the GTB1 subunit of glucosidase II is required for glycoprotein processing in the endoplasmic reticulum, specifically required for the final glucose-trimming event during normal glycoprotein processing 3.2.1.207 additional information glucosidase II is a glycan-processing enzyme that trims two alpha1,3-linked glucose residues from N-glycan on newly synthesized glycoproteins 3.2.1.207 additional information glucosidase II is a glycoprotein-processing enzyme that successively cleaves two alpha1,3-linked glucose residues from N-linked oligosaccharides in the endoplasmic reticulum 3.2.1.207 additional information the enzyme heterodimer is required to efficiently deglucosylate the physiological substrates G2M9 and G1M9
