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
