General annotation (Comments)

Function	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 it weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1 and C5. It cleaves fibrin, fibronectin, thrombospondin, laminin and von Willebrand factor By similarity. UniProtKB P00747
Catalytic activity	Preferential cleavage: Lys-|-Xaa > Arg-|-Xaa; higher selectivity than trypsin. Converts fibrin into soluble products. UniProtKB P00747
Subcellular location	Secreted.
Miscellaneous	Plasmin is inactivated by alpha-2-antiplasmin immediately after dissociation from the clot By similarity. UniProtKB P00747
Sequence similarities	Belongs to the peptidase S1 family. Plasminogen subfamily.
Biophysicochemical properties	pH dependence: Optimum pH is 8. Temperature dependence: Optimum temperature is 40 degrees Celsius.
