Reaction: N4-(β-N-acetyl-D-glucosaminyl)-L-asparagine + H2O = N-acetyl-β-D-glucosaminylamine + L-aspartate
Other name(s): aspartylglucosylamine deaspartylase; aspartylglucosylaminase; aspartylglucosaminidase; aspartylglycosylamine amidohydrolase; N-aspartyl-β -glucosaminidase; glucosylamidase; β -aspartylglucosylamine amidohydrolase
Systematic name: N4-(β-N-acetyl-D-glucosaminyl)-L-asparagine amidohydrolase
Comments: Acts only on asparagine-oligosaccharides containing one amino acid, i.e., the asparagine has free α-amino and α-carboxyl groups [cf. EC 3.5.1.52 peptide-N4-(N-acetyl-β-glucosaminyl)asparagine amidase]
