Bacteroides Heparinase III (also called Heparin Lyase III) is cloned from Bacteroides eggerthii. It is active on both heparin and heparan sulfate.

Bacteroides Heparinase III can cleave the glycosidic bond between hexosamines and either iduronic acid or glucuronic acid residues. It is active in the presence of 6-sulfation. The reaction yields oligosaccharide products containing unsaturated uronic acids, which can be detected by UV spectroscopy at 232 nm

  • Recombinant enzyme with no detectable glycosidase, sulfatase or uronidase contaminating activities 
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 12 months when stored in solution at -80°C
  • Optimal for cleavage of heparan sulfate and heparin with domains of low sulfation
Bacteroides Heparinase III can cleave the glycosidic bond between hexosamines and either iduronic acid or glucuronic acid residues. Bacteroides Heparinase III is active in the presence of 6-sulfation.

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme that will liberate 1.0 μmol unsaturated oligosaccharides from heparan sulfate per minute at 30°C and pH 7.0 in a total reaction volume of 100 μl.

Reaction Conditions

1X Bacteroides Heparinase Reaction Buffer
Incubate at 30°C

Storage Buffer

20 mM Tris-HCl
100 mM NaCl
5 mM CaCl2
1 mM EDTA
pH 7.5 @ 25°C

Heat Inactivation

100°C for 1 minute

Molecular Weight

Unit Assay Conditions

Two fold dilutions of Bacteroides Heparinase III are incubated with 1 mg/ml porcine mucosal heparan sulfate in 1X Bacteroides Heparinase Reaction Buffer, in a 100 μl reaction. The reaction mix is incubated at 30°C. Liberation of unsaturated oligosaccharides is detected by real-time UV spectroscopy at 232 nm.

Notes
  • Avoid repeated freeze-thaw cycles.
  • Typical Reaction Conditions:
    1. Combine 10 μl of 1 mg/ml heparin sulfate, 10 μl Bacteroides heparin Reaction Buffer and H2O in a total reaction volume of 100 μl.
    2. Add 1 μl Bacteroides heparin III.
    3. Incubate reaction at 30°C for 1–24 hours (monitor absorbance at 232 nm for determination of partial or complete digestion).
    Optimal incubation times and enzyme concentrations must be determined empirically for a particular substrate.
FAQs
Tech Tips

  • Heparinase III cleaves less sulfated HS chains.           

    Bacteroides Heparinase III is most active between pH 7.0 - 8.0.

    Bacteroides Heparinase III is calcium dependent and has greatest activity in the presence of 1.5 - 5mM CaCl2.

    Bacteroides Heparinase III can be used in double digests with Bacteroides Heparinase I and II using the Heparinase reaction buffer.
