Heparinase I and III Blend from Flavobacterium heparinum

Heparinase is an inducible, non-extracellular heparin-degrading enzyme. Three types of heparinises are produced by Flavobacterium heparinum and contains specific sequences of heparin.

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

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.
