3.2.1.96

Accepted name:

mannosyl-glycoprotein endo-β-N-acetylglucosaminidase

Reaction:

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

Other name(s):

N,N′-diacetylchitobiosyl β-N-acetylglucosaminidase; endo-β-N-acetylglucosaminidase; mannosyl-glycoprotein endo-β-N-acetylglucosamidase; di-N-acetylchitobiosyl β-N-acetylglucosaminidase; endo-β-acetylglucosaminidase; endo-β-(1→4)-N-acetylglucosaminidase; mannosyl-glycoprotein 1,4-N-acetamidodeoxy-β-D-glycohydrolase; endoglycosidase S; endo-N-acetyl-β-D-glucosaminidase; endo-N-acetyl-β-glucosaminidase; endo-β-N-acetylglucosaminidase D; endo-β-N-acetylglucosaminidase F; endo-β-N-acetylglucosaminidase H; endo-β-N-acetylglucosaminidase L; glycopeptide-D-mannosyl-4-N-(N-acetyl-D-glucosaminyl)₂-asparagine 1,4-N-acetyl-β-glucosaminohydrolase; endoglycosidase H

Systematic name:

glycopeptide-D-mannosyl-N⁴-(N-acetyl-D-glucosaminyl)₂-asparagine 1,4-N-acetyl-β-glucosaminohydrolase
