The Human Lys-Plasminogen was prepared from homogeneous glu-plasminogen by batching with a plasminsepharose column. This resin was removed after activation. This activation results in the release of a 76 amino acid residue peptide (Glu-Lys76). This Lys77-Plasminogen can be readily converted to Lys77-Plasmin by any of the common plasminogen activators. Complete activation was observed by SDS-PAGE. No plasmin activity was detected using the chromogenic assay S-2251.

生化机理
Plasmin dissolves the fibrin of blood clots and acts as a proteolytic factor in a variety of other processes including embryonic development, tissue remodeling, tumor invasion, and inflammation. In ovulation, weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1, C4 and C5. Cleavage of fibronectin and laminin leads to cell detachment and apoptosis. Also cleaves fibrin, thrombospondin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4. Binds to cells. Angiostatin is an angiogenesis inhibitor that blocks neovascularization and growth of experimental primary and metastatic tumors in vivo. (Microbial infection) ENO/enoloase from parasite P.falciparum (strain NF54) interacts with PLG present in the mosquito blood meal to promote the invasion of the mosquito midgut by the parasite ookinete. The catalytic active form, plasmin, is essential for the invasion of the mosquito midgut. (Microbial infection) Binds to OspC on the surface of B.burgdorferi cells, possibly conferring an extracellular protease activity on the bacteria that allows it to traverse host tissue. (Microbial infection) Interacts with dengue virus type 2 particles. Enhances dengue virus type 2 infection in Aedes aegypti mosquito midgut by increasing midgut internalization, resulting in higher infection rates and viral dissemination in mosquitoes.
Post-translational: N-linked glycan contains N-acetyllactosamine and sialic acid. O-linked glycans consist of Gal-GalNAc disaccharide modified with up to 2 sialic acid residues (microheterogeneity). In the presence of the inhibitor, the activation involves only cleavage after Arg-580, yielding two chains held together by two disulfide bonds. In the absence of the inhibitor, the activation involves additionally the removal of the activation peptide. (Microbial infection) The Y.pestis Pla protein cleaves between Arg-580 and Val-581, generating plasmin which facilitates bacterial migration and infection.
