Heparinase III

    Detailed Description

    Research reagent (glycobiology, preparation of oligosaccharide libraries, preparation of disaccharides from heparan sulfate).
    General Information
    Synonyms: Heparin sulfate eliminate; heparin lyase III; heparinase I
    Gene Source: Native Flavobacterium Heparinum
    EC Number: 4.2.2.8
    CAS Number: 37290-86-1
    MDL Number: MFCD00131319
    Catalyzed Reaction: Heparinase III cleaves selectively, via an elimination mechanism, sulfated polysaccharide chains containing 1-4 linkages between hexosamines and glucuronic acid residues. The reaction yields oligosaccharide products (mainly disaccharides) containing unsaturated uronic acids which can be detected by UV spectroscopy at 232 nm. The enzyme is active only towards heparan sulfate and does not cleave heparin or low molecular weight heparins.
    Substrate Specificity: heparan sulfate
    Properties
    Molecular Weight: 70.8 kDa
    Isoelectric point: 9.6 - 9.9
    pH optimum for activity: 7.3
    pH range for activity: 4 - 9
    Optimal temperature range: 20 ℃ - 37 ℃
    Purity: Greater than/equal to 98% by reversed phase HPLC analysis
    Protein Impurities: < 0.1%
    Specific Activity: > 200 IU/mg (max. 235 IU/mg)
    Concentration: 5 IU/mL
    Standard: 0.1 IU, 1.0 IU, or customized standard.
    Unit Definition: One international unit (IU) of heparinase III is defined as the amount of enzyme that will liberate 1.0 μmole unsaturated oligosaccharides from heparan sulfate per minute at 35 ℃ and pH 7.0.
    Stability: Expiration of heparinase III is 12 months from the manufacturing date frozen at – 20 ℃ in PBS.
