Snake-venom alpha-bungarotoxin is a member of the alpha-neurotoxin family that binds with very high affinity to the nicotinic acetylcholine receptor (AChR) at the neuromuscular junction. The structure of the complex between alpha-bungarotoxin and a 13-mer peptide (WRYYESSLEPYPD) that binds the toxin with high affinity, thus inhibiting its interactions with AChR with an IC(50) of 2 nM, has been solved by (1)H-NMR spectroscopy ...
