    Study Notes

    Streptokinase (Fibrinolysin)

    • Converts plasminogen to plasmin, which breaks down fibrin clots.
    • Administered intravenously for coronary, pulmonary, or venous thrombosis.

    Streptodornase (Streptococcal Deoxyribonuclease)

    • Breaks down DNA.

    Hyaluronidase

    • Splits hyaluronic acid, a component of connective tissue.
    • Aids microorganisms in spreading through infected areas (spreading factor).

    Diphosphopyridine Nucleotidaes

    • Associated with the killing of leukocytes (white blood cells).

    Other Enzymes

    • Some strains produce proteinase and amylase.
