Protein

Alpha-mannosidase 2

Gene

Man2a1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the first committed step in the biosynthesis of complex N-glycans. It controls conversion of high mannose to complex N-glycans; the final hydrolytic step in the N-glycan maturation pathway.

Catalytic activityi

Hydrolysis of the terminal (1->3)- and (1->6)-linked alpha-D-mannose residues in the mannosyl-oligosaccharide Man5(GlcNAc)3.

Cofactori

Binds 1 zinc ion per subunit.By similarity
