CC -!- FUNCTION: Specifically deglycosylates the denatured form of N-linked
CC glycoproteins in the cytoplasm and assists their proteasome-mediated
CC degradation. Cleaves the beta-aspartyl-glucosamine (GlcNAc) of the
CC glycan and the amide side chain of Asn, converting Asn to Asp. Prefers
CC proteins containing high-mannose over those bearing complex type
CC oligosaccharides. Can recognize misfolded proteins in the endoplasmic
CC reticulum that are exported to the cytosol to be destroyed and
CC deglycosylate them, while it has no activity toward native proteins.
CC Deglycosylation is a prerequisite for subsequent proteasome-mediated
CC degradation of some, but not all, misfolded glycoproteins (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of an N(4)-(acetyl-beta-D-glucosaminyl)asparagine
CC residue in which the glucosamine residue may be further glycosylated,
CC to yield a (substituted) N-acetyl-beta-D-glucosaminylamine and a
CC peptide containing an aspartate residue.; EC=3.5.1.52;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the transglutaminase-like superfamily. PNGase
CC family. {ECO:0000305}.
