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 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 . Heparinase I neutralizes the protein′s action of anticoagulation. Heparinase I possesses a half-life of 15-18 minutes.

Unit Definition

One unit (Sigma 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.

Pedobacter heparinus (formerly known as Flavobacterium heparinum) is a typical glycosaminoglycan-degrading bacterium that produces three heparin lyases, Hep I, Hep II, and Hep III, which act on heparins with 1,4-glycoside bonds between uronate and amino sugar residues. Being different from
