Aga, aspartylglucosaminidase, glycosylasparaginase
Aspartylglucosaminidase is involved in the catabolism of N-linked oligosaccharides of glycoproteins. It cleaves asparagine from N-acetylglucosamines as one of the final steps in the lysosomal breakdown of glycoproteins. The lysosomal storage disease aspartylglycosaminuria is caused by a deficiency in the AGA enzyme. Alternatively spliced transcript variants have been identified.

Scotti et al., Pavia, Italy. In Recent Pat Anticancer Drug Discov, 2012
[review] Natural killer (NK) cell tumors, subtypes of myeloid leukemias and T-cell lymphomas respond to ASNase; ovarian carcinomas and other solid tumors have been proposed as additional targets for ASNase, with a potential role for glutaminase. activity.
Irreversible inhibitors and activity-based probes as research tools in chemical glycobiology.
Overkleeft et al., Cambridge, United States. In Org Biomol Chem, 2011
Following discussion of some general aspects of the biosynthesis and degradation of N-linked glycoproteins, attention is focused on the enzymes that hydrolyze the protein-carbohydrate linkage, peptide N-glycanase and glycosylasparaginase and their mechanism.

For example, aspartylglucosaminidase (AGA), PLA2, SIAT8B, GALNT7, or B3GAT1 metabolize chemical ligands to which the influenza virus, herpes simplex, cytomegalovirus (CMV), rubella, or Toxoplasma gondii bind.
Plasma lysosomal enzyme activities in congenital disorders of glycosylation, galactosemia and fructosemia.
Dimitriou et al., Athens, Greece. In Clin Chim Acta, 2009

Lysosomal metabolism of glycoproteins.
Winchester, London, United Kingdom. In Glycobiology, 2005
The process is initiated by the removal of any core and peripheral fucose, which is a prerequisite for the action of the peptide N-glycanase aspartylglucosaminidase, which hydrolyzes the glycan-peptide bond.
Elevation of plasma aspartylglucosaminidase is a useful marker for the congenital disorders of glycosylation type I (CDG I).

Jalanko et al., Helsinki, Finland. In Hum Mutat, 2004
A new point mutation, c.44T>G, found in a Finnish compound heterozygote causes a L15R AA substitution in the signal sequence of the AGA enzyme, affecting AGA translocation by altering a critical hydrophobic core structure in the signal sequence.

Adams, Riverside, United States. In Toxicon, 2004
The omega-agatoxins target neuronal calcium channels, modifying their properties in distinct ways, either through gating modification (omega-Aga-IVA) or by reduction of unitary current (omega-Aga-IIIA).
