3.5.1.52 |
| Accepted name: |
peptide-N4-(N-acetyl-β-glucosaminyl)asparagine amidase |
| Reaction: |
Hydrolysis of an N4-(acetyl-β-D-glucosaminyl)asparagine residue in which the glucosamine residue may be further glycosylated, to yield a (substituted) N-acetyl-β-D-glucosaminylamine and a peptide containing an aspartate residue |
| Other name(s): |
glycopeptide N-glycosidase; glycopeptidase; N-oligosaccharide glycopeptidase; N-glycanase; Jack-bean glycopeptidase; PNGase A; PNGase F |
| Systematic name: |
N-linked-glycopeptide-(N-acetyl-β-D-glucosaminyl)-L-asparagine amidohydrolase |
| Comments: |
Does not act on (GlcNAc)Asn, because it requires the presence of more than two amino-acid residues in the substrate [cf. EC 3.5.1.26, N4-(β-N-acetylglucosaminyl)-L-asparaginase]. The plant enzyme was previously erroneously listed as EC 3.2.2.18. |
