Reaction(IUBMB)
Selective cleavage of some Arg! and Lys! bonds, including Lys!Arg and Arg!Ser in (human) kininogen to release bradykinin
Comment
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.
