General annotation (Comments)
| Function | Endoglycosidase which is a cell surface and extracellular matrix-degrading enzyme. Cleaves heparan sulfate proteoglycans (HSPGs) into heparan sulfate side chains and core proteoglycans. Also implicated in the extravasation of leukocytes and tumor cell lines. Contributes to metastasis and angiogenesis By similarity. |
| Enzyme regulation | Inhibited by EDTA and activated by calcium and magnesium By similarity. Inhibited by laminarin sulfate and, to a lower extent, by heparin and sulfamin. |
| Subunit structure | The active heterodimer is composed of the 8 and 50 kDa subunits, the proteolytic products. Ref.2 |
| Subcellular location | Lysosome membrane; Peripheral membrane protein By similarity. Secreted By similarity. Note: Secreted, internalised and transferred to late endosomes/lysosomes as a proheparanase. In lysosomes, it is processed into the active form, the heparanase. The uptake or internalisation of proheparanase is mediated by HSPGs. Heparin appears to be a competitor and retain proheparanase in the extracellular medium By similarity. |
| Post-translational modification | Proteolytically processed. The cleavage of the 65 kDa form leads to the generation of a linker peptide, 8 kDa and 50 kDa product. The active form, the 8/50 kDa heterodimer, is resistant to degradation. Complete removal of the linker peptide appears to be a prerequisite to the complete activation of the enzyme By similarity. N-glycosylated. Glycosylation of the 50 kDa subunit appears to be essential for its solubility. Ref.2 |
| Sequence similarities | Belongs to the glycosyl hydrolase 79 family. |
| biophysicochemical properties | pH dependence: Optimum pH is 5. |
