Snake Venom Bungarotoxin
Protein Data Bank ID: 1HC9
Protein Name: alpha-Bungarotoxin
Organism: Bungarus multicinctus
Title of Drawing: “Seal and Cats”
α-Bungarotoxin is a snake venom from the elapid Bungarus multicinctus. It irreversibly binds the acetylcholine receptor which is the main receptor at the neuromuscular junction. Thereby it permits the binding of the acetylcholine molecule which is responsible for signal transfer into muscles. Thus, alpha-bungarotoxin causes muscle paralysis which than results in respiratory failure and consequently in the death of the victim.
