General annotation (Comments)

Function

Involved in the maturation of Asn-linked oligosaccharides. Progressively trims alpha-1,2-linked mannose residues from Man9GlcNAc2 to produce Man5GlcNAc2 By similarity.

Catalytic activity

Hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in the oligo-mannose oligosaccharide Man9(GlcNAc)2.

Cofactor

Ca2+. Can also use Mg2+, but with lower efficiency By similarity.

Pathway

Protein modification; protein glycosylation.

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasmic vesicle lumen By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 47 family.
