Product Name
Recombinant Flavobacterium heparinum Heparinase II protein
Product Overview
Recombinant Flavobacterium heparinum Heparinase II was expressed in E. coli
Description
Heparin and heparan sulfate are linear, negatively charged polymers consisting of repeating units of 1→4-linked uronic acid (l-iduronic acid (IdoA) and d-glucuronic acid (GlcA)) and glucosamine. Neutralization of the anticoagulant effect of heparin and determination of plasma levels of heparin has been problematic, and the use of heparin during extracorporeal therapies can result insevere haemorrhagic complications. The eliminative depolymerization of heparin/heparan sulfate affording unsaturated oligosaccharide products is carried out by three families of enzymes. Their primary sequences show no recognizable similarity, and they have distinct specificities. Thus, heparinase I is specific for heparin cleaving the glycosidic linkage to the nonreducing end of IdoA, heparin lyase III (heparinase III) cleaves the heparan sulfate next to glucuronic acid, and heparin lyase II (heparinase II) can depolymerize both of these substrates.
