      Description
      OverviewNative N-Glycosidase F from Elizabethkingia meningosepticum. Catalyzes the hydrolysis of asparagine-linked high mannose, as well as hybrid and complex oligosaccharides from glycoproteins. This enzyme will not cleave oligosaccharides containing α1,3-linked core fucose commonly found on plant glycoproteins. N-Glycosidase F will also fail to cleave if the asparagine to which the oligosaccharide is attached is not peptide-bonded to at least one amino acid residue at both the amino and carboxy termini.

This enzyme will not cleave oligosaccharides containing α1-3-linked core fucose commonly found on plant glycoproteins.

      Recommended reaction conditions
      Note: This protocol is provided only as a general guideline. Researchers should standardize this assay for their own specific needs and should consult published literature. N-glycosidase F cleaves asparagine-linked high mannose, as well as hybrid and complex oligosaccharides, from glycoproteins. It deaminates the asparagine to aspartic acid, but leaves the oligosaccharide intact. N-glycosidase F will not remove oligosaccharides containing α1,3-linked core fucose commonly found on plant glycoproteins. In addition, N-glycosidase F will not cleave if the asparagine to which the oligosaccharide is linked is not peptide bonded to at least one amino acid residue at both the N- and C-termini. Detergent and heat denaturation increase the rate of cleavage up to 100X. Most native proteins can still be completely N-deglycosylated but the incubation time must be increased. N-glycosidase F will remain active under the recommended incubation conditions for at least 72 h. Assay for Unit Definition One unit of N-glycosidase F is defined as the amount of enzyme that will catalyze the release of N-linked oligosaccharides from 1 nmol of denatured Ribonuclease B per min at 37°C, pH 7.5. Cleavage is monitored by SDS-PAGE. One unit of Nglycosidase F is equal to 1 IUB milliunit. Required Reagents • Substrate: Ribonuclease B at a concentration of 1.1 mg/ml in 1X assay buffer • Enzyme: Dilute the preparation of N-glycosidase F 1:400 in 1X assay buffer • 5X Assay Buffer: 250 mM NaHPO4, pH 7.5 • Denaturation buffer: 2% SDS, 1 M β-mercaptoethanol (β-ME) • dH2O • SDS-PAGE system • Triton® X-100 detergent (Cat. No. 648463) Protocol 1. Add 25 µl of denaturation buffer to 0.45 ml of substrate solution and heat to 100°C for 10 min. Cool and add 25 µl of Triton® X-100 detergent. 2. Add 50 µl (50 µg) of denatured substrate to each of 6 tubes. 3. Add 0, 1, 2, 3, 4, or 5 µl of diluted enzyme to appropriately labeled tubes and incubate 1 h at 37°C. 4. Stop the reaction by heating to 100°C for 5 min. 5. Run 10 µl of each sample on a 12% SDS-PAGE gel. Stain with Coomassie Blue. Ribonuclease B is ~15 kD. Note the lowest tube number in which ~50% of the substrate is cleaved. 6. Calculate the activity: Units/ml = (4 X 108) R\M T V R = 25 (µg of Ribonuclease B cleaved) M = 15,000 (formula weight of Ribonuclease B) T = 60 (time in min) V = volume (µl) of enzyme dilution needed to cleave 50% For example, if 2 µl of enzyme resulted in 50% cleavage, the activity would be 5,540 units/ml. Assay for Deglycosylation Required Reagents • Glycoprotein substrate • N-glycosidase F • 5X Assay Buffer: 250 mM NaHPO4, pH 7.5 • Denaturation buffer: 2% SDS, 1 M β-mercaptoethanol (β-ME) • dH2O • SDS-PAGE system • Triton® X-100 detergent (Cat. No. 648463) Protocol 1. Add up to 200 µg of glycoprotein to an eppendorf tube. Adjust the final volume to 35 µl with dH2O. 2. Add 10 µl of 5X assay buffer and 2.5 µl of denaturation buffer. Heat to 100°C for 5 min. 3. Cool the tube and add 2.5 µl of Triton® X-100 detergent and mix. Note: Failure to add Triton® X-100 detergent will result in a 3-fold reduction of N-glycosidase F activity. 4. Add 2 µl of N-glycosidase F to the reaction. Incubate for 3 h at 37°C. Note: If SDS or heat denaturation is omitted, it may be necessary to increase the incubation time to at least 24 h 5. Monitor the cleavage by SDS-PAGE.
