Plasma kallikrein is a protein that in humans is encoded by the KLKB1 gene.Plasma prekallikrein is a glycoprotein that participates in the surface-dependent activation of blood coagulation fibrinolysis kinin generation and inflammation. It is synthesized in the liver and secreted into the blood as a single polypeptide chain. Plasma prekallikrein is converted to plasma kallikrein by factor XIIa by the cleavage of an internal Arg-Ile bond.
