Protein attributes

Sequence length	346 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.
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	Lysosome.
Involvement in disease	Defects in AGA are the cause of aspartylglucosaminuria (AGU) [MIM:208400]. AGU is an inborn lysosomal storage disease. Clinical features of AGU include mild to severe mental retardation manifesting from the age of 2, coarse facial features and mild connective tissue abnormalities. This recessively inherited disease is overrepresented in the Finnish population. Ref.3 Ref.5 Ref.6 Ref.16 Ref.17 Ref.18
Sequence similarities	Belongs to the Ntn-hydrolase family.
