Plasma kallikrein.
based on mapping to UniProt P03952
Cleaves selectively Arg-|-Xaa and Lys-|-Xaa bonds, including Lys-|-Arg and Arg-|-Ser bonds in (human) kininogen to release bradykinin.
-!- Formed from plasma prokallikrein (Fletcher factor) by factor XIIa. -!- Activates coagulation factors XII, VII and plasminogen. -!- Selective for Arg > Lys in P1, in small molecule substrates. -!- Belongs to peptidase family S1. -!- Formerly EC 3.4.4.21 and EC 3.4.21.8.
