Term: plasmin
Literally meaning: “plasma protein”
Origin: Anc Greek
πλάσμα(noun)/plasma (=something formed or molded, an idol) > πλάσσω/plasso(=create, form, mold)
Coined/History
In 1933
Tillett and Garner discovered a fibrinolytic component contained within a broth
culture of haemolytic Streptococci. In 1949 Tillett with Sol Sherry named this
component streptokinase (SK) and administered this to patients for treatment of
fibrinous adhesions. By 1957 the active
form of this enzyme was called plasmin and its inactive form plasminogen.

Definition
Plasmin is
a proteolytic enzyme for blood plasma proteins especialy for fibrin clots, after
its activation of its proenzyme form, the plasminogen. Human plasmin is encoded by PLG gene and gene mutations may cause
thrombosis.
