Accepted name: plasmin

Reaction: Preferential cleavage: Lys > Arg; higher selectivity than trypsin. Converts fibrin into soluble products

Other names: fibrinase; fibrinolysin; actase; serum tryptase; thrombolysin

Comments: Formed from plasminogen by proteolysis which results in multiple forms of the active plasmin. In peptidase family S1 (trypsin family). Formerly EC
