Enzyme Information

Mannosyl-oligosaccharide glucosidase.
based on mapping to UniProt P53008
Glc(3)Man(9)GlcNAc(2)-[protein] + H(2)O = Glc(2)Man(9)GlcNAc(2)-[protein] + beta-D-glucopyranose.
-!- This enzyme catalyzes the first step in the processing of the N-glycan tetradecasaccharide precursor Glc(3)Man(9)GlcNAc(2), which takes place in the endoplasmic reticulum, by removing the distal alpha-1,2-linked glucose residue. -!- This and subsequent processing steps are required before complex N-glycans can be synthesized.
