일반 설명
Heparinase II is one of three key heparin-degrading enzymes of Flavobacterium heparinum (also known as Pedobacter heparinus1). It belongs to the polysaccharide lyases family PL21.
애플리케이션
Heparinase II from Flavobacterium heparinum has been used:
- for digestion of heparin sulfate during exosome isolation
- for digestion of heparin sulfate in notochordal cell conditioned media (NCCM) to investigate the content of glycosaminoglycans in NCCM
- as a component of digestion buffer during cell surface glycan processing
- as a component of heparin lyase (HSase) mix to remove the heparin sulfate on the 293ͰT/ACE2 cell surface and study the effect of histones on the infectivity of pseudovirus
생화학적/생리학적 작용
Heparinase II cleaves heparan sulfate, and to a lesser extent heparin (relative activity about 2:1), at the α (1-4) linkages between hexosamines and uronic acid residues (both glucuronic and iduronic), yielding mainly disaccharides. Heparinase II has the broadest substrate specificity of the three heparinases Heparinase enzymes helps in decoding the complex structures of substrates. Heparin interferes with DNA transcription in PCR and in reverse transcription of RNA. Heparinase II has been used to remove heparin for downstream analysis of genomic DNA.
단위 정의
One unit will form 0.1 μmole of unsaturated uronic acid per hr at pH 7.0 at 25 °C. One International Unit (I.U.) is equivalent to approx. 600 Sigma units.

Heparinase II (HepII) is an 85-kDa dimeric enzyme that depolymerizes both heparin and heparan sulfate glycosaminoglycans through a beta-elimination mechanism. Recently, we determined the crystal structure of HepII from Pedobacter heparinus (previously known as Flavobacterium heparinum) in complex with a
