Protein

Endoplasmic reticulum mannosyl-oligosaccharide 1,2-alpha-mannosidase

Gene

MAN1B1

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in glycoprotein quality control targeting of misfolded glycoproteins for degradation. It primarily trims a single alpha-1,2-linked mannose residue from Man9GlcNAc2 to produce Man8GlcNAc2, but at high enzyme concentrations, as found in the ER quality control compartment (ERQC), it further trims the carbohydrates to Man5-6GlcNAc2.2 Publications

Catalytic activityi

Hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in the oligo-mannose oligosaccharide Man9(GlcNAc)2.3 Publications

Cofactori

Enzyme regulationi

Inhibited by both 1-deoxymannojirimycin (dMNJ) and kifunensine.1 Publication

Kineticsi

  1. KM=0.4 mM for Man9GlcNAc21 Publication

pH dependencei

Optimum pH is between 6.5 and 6.9.1 Publication
