Peptide: N-Glycosidase F, also known as PNGase F, is an amidase which is supplied glycerol free for optimal performance in HPLC intensive methods. PNGase F cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid and complex oligosaccharides from N-linked glycoproteins (1).

PNGase F is not able to cleave N-linked glycans from glycoproteins when the innermost GlcNAc residue is linked to an α1-3 Fucose residue (2). This modification is most commonly found in plant and some insect glycoproteins.

Product Source

PNGase F is purified from Flavobacterium meningosepticum (3), free of contaminants (Endo F, proteases, etc.).

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 10 µg of denatured RNase B in 1 hour at 37°C in a total reaction volume of 10 µl.

Unit Definition Assay:
10 µg of RNase B are denatured with 1X Glycoprotein Denaturing Buffer (0.5% SDS, 40 mM DTT) at 100°C for 10 minutes. After the addition of NP-40 and GlycoBuffer 2, two-fold dilutions of PNGase F are added and the reaction mix is incubated for 1 hour at 37°C. Separation of reaction products are visualized by SDS-PAGE.

Notes

Since PNGase F activity is inhibited by SDS, it is essential to have NP-40 present in the reaction mixture. Why this non-ionic detergent counteracts the SDS inhibition is unknown at present.
To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required.
PNGase F will not cleave N-linked glycans containing core α1-3 Fucose.
Repeated freeze thaw cycles degrade enzyme activity over time.
Typical reaction conditions: Please see Protocol tab

Tech Tips

Don’t freeze-thaw this enzyme.
You can use this enzyme under native or denaturing conditions.
Under native conditions we recommend adding more enzyme and using longer incubation times.
PNGase F activity is inhibited by SDS, therefore under denaturing conditions it is essential to have NP-40 present in the reaction mixture in a 1:1 ratio.
PNGase F will not cleave N-linked glycans containing core α1-3 Fucose (PNGase A must be used in this instance).
