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 tissuesP0 retinaedigestion

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.

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.
