Background: Heparinase II

Heparan sulfate is a sulfated glycosaminoglycan with the repeating disaccharide units of ‑4HexA1,4GlcNAc beta1-. It is usually attached to the protein cores of proteoglycans found on cell membrane and extracellular matrix, where it binds to a variety of protein ligands and regulates a wide range of biological activities, including developmental processes, angiogenesis, blood coagulation and tumor metastasis (1, 2). Heparan sulfate has a domain structure containing sulfated regions interspaced with less or non-sulfated regions (3, 4). Heparin shares the backbone structure with heparan sulfate but contains no non-sulfated regions. Heparinases are a family of lyases that release unsaturated oligosaccharides from heparin and heparan sulfate upon digestion (5). Heparinase I recognizes highly sulfated regions and is more specific for heparin. Heparinase II digests both heparin and heparan sulfate. Heparinase III prefers less-sulfated regions and is active only on heparan sulfate (6, 7).
