Protein

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

Gene

MNS1

Organism

Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Involved in glycoprotein quality control as it is important for the 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 it further trims the carbohydrates to Man₅GlcNAc₂.1 Publication

Miscellaneous

Present with 8260 molecules/cell in log phase SD medium.1 Publication

Catalytic activityⁱ

Hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in the oligo-mannose oligosaccharide Man₉(GlcNAc)₂.1 Publication

Cofactorⁱ

Ca²⁺1 Publication

Pathwayⁱ: protein glycosylation

This protein is involved in the pathway protein glycosylation, which is part of Protein modification.1 Publication
View all proteins of this organism that are known to be involved in the pathway protein glycosylation and in Protein modification.
