N-Glycosidase A from sweet almond meal Roche

EC 3.5.1.52
Optimum pH: 4.0 - 6.0
Molecular weight: M_r = 52.5 kD
Specific activity: approx. >0.5 U/mg protein. 1 U hydrolyzes 1 µmol ovalbumin glycopeptide (glu-glu-lys-tyr-asn(CHO)-leu-thr-ser-val) within 1 min at 37°C and pH 5; CHO represents hybrid- and high-mannose type oligosaccharides
Specificity: Hydrolyzes all types of N-glycan chains from glycopeptides, even those carrying α1,3-bound core fucose residues present in insect and plant glycoproteins

Solution in 50 mM citrate/phosphate buffer, 50% glycerol (v/v),
pH 5.0

Absence of contaminants: proteases are not detectable.
Contaminants:α- and β-galactosidase, α- and β-mannosidase, β-glucosidase, β-N-acetylhexosaminidase, α-L-fucosidase, sialidase and β-xylosidase, each <0.1%
