BRITE hierarchy
Reaction(IUBMB)
Specific cleavage of Arg!Val bond in plasminogen to form plasmin
Comment
A peptidase of family S1 (trypsin family) from a wide variety of mammalian tissues, especially endothelial cells. Secreted as a single chain precursor which is cleaved to a two-chain form by plasmin. Activity is considerably enhanced by fibrin. Formerly included in EC 3.4.21.31 and EC 3.4.99.26
