Crotoxin

Venom is the mark of a special club, a select subset of the animal kingdom. It includes vipers, jellyfish, spiders, scorpions, centipedes, bees, cone snails, newts, platypus, and even a primate. All these animals produce molecules that attack a victim in minutes or even seconds. The molecules are intricately complex, with shapes that allow them to precisely lock onto certain proteins on our own cells. Depending on its exact target in the body, venom will paralyze nerves, rot muscles, and stop blood from clotting.

Crotoxin (CTX), a phospholipase A2 neurotoxin constituted by the association of two subunits, exerts its lethal action by blocking neuromuscular transmission.
