Function
A kallikrein-like protease. It preferentially converts human high-molecular-weight kininogen (HK) to bradykinin. Displays broad substrate specificity in vitro, with highest activity toward Boc-Val-Leu-Lys-MCA, Boc-Glu-Lys-Lys-MCA, Boc-Glu(OBzl)-Ala-Arg-MCA, Boc-Val-Pro-Arg-MCA, ZPhe-Arg-MCA and Pro-Phe-Arg-MCA. Has preference for Arg and Lys in position P1 and hydrophobic residues in position P2. Is not toxic to mice.
