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
