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
Sold on the basis of Heparinase I units

One unit will form 0.1 micromole of unsaturated uronic acid per hour at 7.5 at 25 degrees C using Heparin, Sodium as substrate for heparinase I.
One unit will form 0.1 micromole of unsaturated uronic acid per hour at 7.5 at 25 degrees C using bovine kidney Heparan, Sulfate as substrate for heparinase III.
One unit will form 0.1 μmole of unsaturated uronic acid per hr at pH 7.5 at 25 °C. One International Unit (I.U.) is equivalent to approx. 600 Sigma units. Package sizes are sold in Sigma units.

Neovascularization is associated with the regulation of tissue development, wound healing, and tumor metastasis. A number of studies have focused on the role of heparin-like molecules in neovascularization; however, little is known about the role of heparin-degrading enzymes in neovascularization.
