Target type: molecularfunction
Catalysis of the reaction: N(4)-(beta-N-acetyl-D-glucosaminyl)-L-asparagine + H2O = N-acetyl-beta-D-glucosaminylamine + L-aspartate + H+. [EC:3.5.1.26, RHEA:11544]
N4-(beta-N-acetylglucosaminyl)-L-asparaginase activity refers to the enzymatic hydrolysis of the glycosidic bond between N-acetylglucosamine and asparagine in the N-linked glycans of glycoproteins. This activity is critical for the processing and maturation of glycoproteins, which play diverse roles in cell signaling, immune function, and protein folding. Specifically, this enzyme removes the terminal N-acetylglucosamine residue from the N-linked glycan, a step essential for the subsequent processing by other glycosidases. The resulting oligosaccharide chain then undergoes further modifications, including trimming, branching, and the addition of other sugars, leading to the formation of diverse and functionally relevant glycan structures.'

| Compound | Definition | Classes | Roles |
|---|---|---|---|
| succinic acid | succinic acid : An alpha,omega-dicarboxylic acid resulting from the formal oxidation of each of the terminal methyl groups of butane to the corresponding carboxy group. It is an intermediate metabolite in the citric acid cycle. Succinic Acid: A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent.
