Ons trigger an activation of the contact system more potently than strains isolated from noninvasive infections. The present study gives new insights into the mechanisms by which S. pyogenes triggers the human contact system and stresses the function of soluble and surface located plasmin exploited as a group A streptococcal virulence factor through the action of streptokinase. treptococcus pyogen
Secrete streptokinase in order to accelerate the conversion of human plasminogen to plasmin (12). Lacking enzymatic activity itself, streptokinase evolves its function by forming a stoichiometric 1:1 complex with plasminogen or a trimolecular complex with plasminogen and fibrinogen. The activator complexes can bind at the bacterial surface via host factor receptors and convert other plasminogen mo
