    One of the main challenges in snakebite envenomation treatment is the development of stable, versatile and efficient anti-venom therapies. Local myotoxicity in accidents involving snakes from the Bothrops genus is still a consequence of serum therapy inefficient neutralization that may lead to permanent sequelae in their victims. One of the classes of toxins that participate in muscle necrosis is the PLA 2 -like proteins. The aim of this work was to investigate the role of zinc ions in the inhibition of PLA 2 -like proteins and to advance the current knowledge of their action mechanism.
