Protein
Alpha-mannosidase 2x
Gene
MAN2A2, MANA2X
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript 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.
