Organism	Elizabethkingia miricola (Chryseobacterium miricola)
Taxonomic identifier	172045 [NCBI]
Taxonomic lineage	Bacteria › Bacteroidetes › Flavobacteria › Flavobacteriales › Flavobacteriaceae › Elizabethkingia

Protein attributes

Sequence length	340 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

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	N(4)-(beta-N-acetyl-D-glucosaminyl)-L-asparagine + H2O = N-acetyl-beta-D-glucosaminylamine + L-aspartate.
Subunit structure	Heterotetramer of two alpha and two beta chains arranged as a dimer of alpha/beta heterodimers.
Subcellular location	Periplasm.
Sequence similarities	Belongs to the Ntn-hydrolase family.
