General annotation (Comments)

Function

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

Catalytic activity

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

Cofactor

Calcium.

Enzyme regulation

Inhibited by both 1-deoxymannojirimycin and kifunensine By similarity.

Pathway

Protein modification; protein glycosylation.

Subcellular location

Golgi apparatus membrane; Single-pass type II membrane protein.

Post-translational modification

N-linked glycan at Asn-515 consists of Man(6)-GlcNAc2.

Sequence similarities

Belongs to the glycosyl hydrolase 47 family.
