Reaction(IUBMB)
Specific cleavage of Arg!Val bond in plasminogen to form plasmin
Comment
Formed from the inactive precursor by action of plasmin or plasma kallikrein. Differs in structure from t-plasminogen activator (EC
3.4.21.68 ), and does not bind to fibrin. In peptidase family S1 (trypsin family). Formerly included in EC
3.4.21.31 and EC
3.4.99.26
History
EC 3.4.21.73 created 1972 as EC 3.4.99.26, transferred 1978 as EC 3.4.21.31, part transferred 1992 to EC 3.4.21.73
Orthology
