Wikipedia
Bungarotoxin

Bungarotoxins are a group of closely related neurotoxic proteins derived from the venom of kraits including Bungarus multicinctus. α-Bungarotoxin inhibits the binding of acetylcholine (ACh) to nicotinic acetylcholine receptors; β- and γ-bungarotoxins act presynaptically causing excessive acetylcholine release and subsequent depletion. Both α and β forms have been characterized, the α being similar to the long or Type II neurotoxins from other elapid venoms.

There are four types:

  • α-Bungarotoxin
  • β-Bungarotoxin
  • γ-Bungarotoxin
  • k-Bungarotoxin
