General annotation (Comments)

Function

Class I alpha-mannosidase essential for early N-glycan processing. Removes preferentially alpha-1,2-linked mannose residues from Man9GlcNAc2 to produce Man8GlcNAc2. Involved in root development and cell wall biosynthesis. Ref.4

Catalytic activity

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

Cofactor

Calcium or manganese. Magnesium can be used to a lesser extent.

Enzyme regulation

Inhibited by kifunensine and 1-deoxymannojirimycin, but not by swainsonine. Ref.4

Pathway

Protein modification; protein glycosylation.

Subcellular location

Golgi apparatuscis-Golgi network membrane Probable; Single-pass type II membrane protein Ref.4.

Tissue specificity

Expressed in flowers, siliques, stems, leaves, roots, stamens and sepals. Ref.4

Disruption phenotype

Formation of aberrant N-glycan structures. Ref.4

Sequence similarities

Belongs to the glycosyl hydrolase 47 family.

Sequence caution

The sequence AAG52061.1 differs from that shown. Reason: Erroneous gene model prediction.
