Southeast Asian banded krait

The venom of the elapid snake Bungarus multicinctus (Southeast Asian banded krait) contains a-bungarotoxin, a protein composed fo 74 amino acids (about 8000 daltons) having five disulfide bridges. The LD50 in mice is 0.21 mg/g (s.c.)... 

The venom of the Southeast Asian banded krait (Bungarus multicinctus) contains a-bungarotoxin, which binds exclusively and by high affinity to the nicotinic receptors. By means of these and many other substances, it is unveiled that insects and other invertebrates like the vertebrates have both types of acetylcholine receptors.
