Short name: Glucosidase_2_bsu

Overlapping homologous superfamilies


Family relationships



Glucosidase II catalyses the sequential removal of two alpha-1,3-linked glucose residues in the second step of N-linked oligosaccharide processing. It is a heterodimer whose alpha subunit bears the glycosyl hydrolase active site, while its beta subunit role is controversial. The beta subunit has been reported to be involved in the solubility and stability of the heterodimeric enzyme, and in retaining the enzyme within the endoplasmic reticulum [PMID: 10929008]. Other studies suggest that the beta subunit modulates N-Glycan trimming in both fission yeast and mammals [PMID: 16373354, PMID: 19542522, PMID: 19605557].
