Heparinase III Protein, P. heparinus (His)

Heparinase III Protein is the unique member of the heparinase family of heparin-degrading lyases that recognizes the ubiquitous cell-surface heparan sulfate proteoglycans as its primary substrate. Heparinase III functions in cleaving metazoan heparan sulfate and providing carbon, nitrogen and sulfate sources for microorganisms. Furthermore, Heparinase III is cardioprotective in a dose-dependent manner, preserves endothelial function and attenuates PMN adherence to the coronary vascular endothelium. Heparinase III Protein, P. heparinus (His) is the recombinant Heparinase III protein, expressed by E. coli , with N-6*His labeled tag. The total length of Heparinase III Protein, P. heparinus (His) is 635 a.a., with molecular weight of ~74 kDa.

Heparinase III is the unique member of the heparinase family of heparin-degrading lyases that recognizes the ubiquitous cell-surface heparan sulfate proteoglycans as its primary substrate. Heparinase III functions in cleaving metazoan heparan sulfate and providing carbon, nitrogen and sulfate sources for microorganisms. Heparinase III specifically cleaves heparan sulfate-rich regions of acidic polysaccharides. It acts primarily at the glycosidic linkage between N-sulfated or N-acetylated glucosamine (GlcNS or GlcNAc) and glucuronic acid (GlcA) as primary sites on the condition that the C2 GlcA is not sulfated. It can limit proliferation by affecting heparan sulfate proteoglycan binding growth factors following arterial injury. Furthermore, Heparinase III is cardioprotective in a dose-dependent manner, preserves endothelial function and attenuates PMN adherence to the coronary vascular endothelium^[1][2][3][4].

Measured by its ability to liberate oligosaccharides from heparin. Which can be measured by absorbance at 232 nm. The specific activity is 432.279935 pmol/min/µg, as measured under the described conditions.
