Target type: molecularfunction
Catalysis of the endohydrolysis of the N,N'-diacetylchitobiosyl unit in high-mannose glycopeptides and glycoproteins containing the -[Man(GlcNAc)2]Asn-structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact. [EC:3.2.1.96]
Mannosyl-glycoprotein endo-beta-N-acetylglucosaminidase activity is a molecular function that involves the hydrolysis of the beta-1,4-glycosidic bond between N-acetylglucosamine (GlcNAc) and mannose residues in N-linked glycans. Specifically, this enzyme cleaves the chitobiose core (GlcNAc-beta-1,4-GlcNAc) from the asparagine-linked oligosaccharide chains of glycoproteins. This activity is critical for the processing and degradation of glycoproteins, as it can remove glycans from glycoproteins, thereby affecting their structure, function, and stability. It plays a role in various cellular processes, including protein folding, trafficking, and degradation. In addition, it is involved in the biosynthesis of certain glycoproteins and can modify the glycosylation patterns of glycoproteins, potentially affecting their biological activity.'
