General description
Heparinase is an inducible, non-extracellular heparin-degrading enzyme. Three types of heparinises are produced by Flavobacterium heparinum and contains specific sequences of heparin.
Application
Heparinase I and III Blend from Flavobacterium heparinum has been used in:
- the digestion of heparan sulfate from ovine vitreous
- human embryonic kidney cells
- glycosaminoglycans from arterial tissues
- P0 retinae digestion
Biochem/physiol Actions
Heparin-degrading lyase that recognizes heparin sulfate proteoglycan as its primary substrate.
Heparinase I and III plays vital role in various biological processes: modulate cell-growth factor interactions, cell-lipoprotein interactions, neovascularization. It cleaves highly sulphated polysaccharide chains in presence of 2-O-sulfated α-L-idopyranosyluronic acid and β-D-glucopyranosyluronic acid residues of polysaccharides.
Packaging
