UniProt functional annotation for Q47898

UniProt code: Q47898.

Organism: Elizabethkingia miricola (Chryseobacterium miricola).
Taxonomy: Bacteria; Bacteroidetes; Flavobacteriia; Flavobacteriales; Weeksellaceae; Elizabethkingia.
 
Function: Cleaves the GlcNAc-Asn bond which joins oligosaccharides to the peptide of asparagine-linked glycoproteins. Requires that the glycosylated asparagine moiety is not substituted on its N-(R1) and C- (R2) terminus.
 
Catalytic activity: Reaction=H2O + N(4)-(beta-N-acetyl-D-glucosaminyl)-L-asparagine = H(+) + L-aspartate + N-acetyl-beta-D-glucosaminylamine; Xref=Rhea:RHEA:11544, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15947, ChEBI:CHEBI:29991, ChEBI:CHEBI:58080; EC=3.5.1.26;
Subunit: Heterotetramer of two alpha and two beta chains arranged as a dimer of alpha/beta heterodimers. {ECO:0000269|PubMed:10490104, ECO:0000269|PubMed:17157318, ECO:0000269|PubMed:20800597, ECO:0000269|PubMed:9685368}.
Subcellular location: Periplasm.
Ptm: Cleaved into an alpha and beta chain by autocatalysis; this activates the enzyme. The N-terminal residue of the beta subunit is responsible for the nucleophile hydrolase activity.
Similarity: Belongs to the Ntn-hydrolase family. {ECO:0000305}.
