Application

Heparinase I from Flavobacterium heparinum has been used:in the digestion of plasma samples to study the effect of medium, washing and sonication on the infectivity of Chlamydia pneumoniain enzymatic removal of heparan sulfate from the surface of human rhabdomyosarcoma cells

Biochem/physiol Actions

Heparinase I from Flavobacterium heparinum acts by cleaving the α-glycoside linkage at AT III binding site in heparin. This results in small oligosaccharide fragments . Heparinase I neutralizes the protein′s action of anticoagulation. Heparinase I possesses a half-life of 15-18 minutes.
