Category
| Application | Structural analysis of O-glycan |
|---|---|
| Concentration | ≥2 U/mL |
| Enzyme Applications|MultiLine | PNGaseF is used to release intact N-linked glycans from glycopeptides and glycoproteins|preparation of deglycosylated proteins for molecular weight estimation or crystallography studies|structure-function studies of N-glycosylated glycoproteins| |
| Enzyme Formulation | 52 mM Tris-HCl, 36 mM NaCl, 9 mM sodium acetate, 5 mM EDTA, 0.02% sodium azide (pH 7.5), glycerol-free formulation |
| Enzyme Source | Native, purified from Elizabethkingia meningoseptica. The source organism was previously known as Chryseobacterium [Flavobacterium] meningosepticum |
| Enzyme Specificity | PNGase F releases intact N-linked oligosaccharides from glycoproteins and glycopeptides. The enzyme will not cleave oligosaccharides from a single asparagine residue and cleavage does not occur if there is core α1-3 linked fucose as commonly encountered in plant glycoproteins Phosphate, sulfate and sialic acid groups attached to the oligosaccharide do not affect cleavage. |
| Enzyme Unit Definition | One unit of N-Glycanase is defined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 μmole of denatured ribonuclease B per minute at pH 7.5 and 37°C |
