Description
OverviewRecombinant, streptomyces plicatus endoglycosidase H expressed in E. coli. Catalyzes the hydrolysis of asparagine-linked oligomannose and hybrid, but not complex oligosaccharides from glycoprotein. Endo H cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide.
Note: 1 mU = 1 milliunit.

    Recommended reaction conditions
    Endoglycosidase H, Streptomyces plicatus, Recombinant, E. coli 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. Endoglycosidase H cleaves asparagine-linked oligomannose and hybrid, but not complex, oligosaccharides from glycoproteins. It cleaves between the two Nacetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, N-glycosidase F (Cat. No. 362185) removes the oligosaccharide intact. Detergent and heat denaturation may increase the rate of cleavage for some glycoproteins. Required Reagents Substrate: Ribonuclease B at a concentration of 1.1 mg/ml in 1X assay buffer Enzyme: Dilute the preparation of Endoglycosidase H 1:400 in 1X assay buffer 5X Assay Buffer: 250 mM NaHPO4, pH 5.5 Denaturation buffer: 2% SDS, 1 M β-mercaptoethanol (β-ME) dH2O SDS-PAGE system 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 dH2O. 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 510) 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 5.55 units/ml. Assay for Deglycosylation Required Reagents Glycoprotein substrate Endoglycosidase H 5X Assay Buffer: 250 mM NaHPO4, pH 5.5 Denaturation buffer: 2% SDS, 1 M β-mercaptoethanol (β-ME) dH2O SDS-PAGE system Protocol 1. Add up to 200 µg of glycoprotein to an eppendorf tube. Adjust the final volume to 37.5 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. Note: It is not necessary to add Triton® X-100 detergent. SDS will not inactivate the Endoglycosidase H 3. Cool the tube and add 2 µl of Endoglycosidase H 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. 4. Monitor the cleavage by SDS-PAGE.
