CC -!- FUNCTION: Cleaves the GlcNAc-Asn bond which joins oligosaccharides to
CC the peptide of asparagine-linked glycoproteins.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(4)-(beta-N-acetyl-D-glucosaminyl)-L-asparagine = H(+)
CC + L-aspartate + N-acetyl-beta-D-glucosaminylamine;
CC Xref=Rhea:RHEA:11544, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15947, ChEBI:CHEBI:29991, ChEBI:CHEBI:58080; EC=3.5.1.26;
CC -!- SUBUNIT: Heterotetramer of two alpha and two beta chains or heterodimer
CC of an alpha and a beta chain.
CC -!- SUBCELLULAR LOCATION: Lysosome.
CC -!- PTM: Cleaved into an alpha and beta chain by autocatalysis; this
CC activates the enzyme. The N-terminal residue of the beta subunit is
CC responsible for the nucleophile hydrolase activity (Probable).
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the Ntn-hydrolase family. {ECO:0000305}.
