H2519 Sigma-Aldrich

Heparinase I from Flavobacterium heparinum

Lyophilized powder stabilized with approx. 25% bovine serum albumin, ≥200 units/mg protein (enzyme + BSA)

Synonym: Heparin lyase I, Heparinase




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 pneumonia
• in 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 and heparinase I neutralizes the protein′s action of anticoagulation. Therefore it might replace the use of protamine in reversing heparin induced anticoagulation after coronary artery bypass surgery. Heparinase I possesses a half-life of 15-18 minutes.

Unit Definition

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.
