Inoculating horses with nonlethal doses of snake venom induces the horses to produce antibodies to the snake venom (antivenom), but the Fc portions of horse antibodies are recognized as foreign by human immune systems and can produce allergic/anaphylactic reactions in sensitized persons. A safter antivenom uses F(ab’)2 antivenom with the Fc portion removed. Which of these enzymes can convert a horse anti-snake venom IgG antibody into an F(ab’)2 antivenom?
