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 | |
| Subcellular location | Golgi apparatus membrane; Single-pass type II membrane protein. |
| Sequence similarities | Belongs to the glycosyl hydrolase 47 family. |
