Of snakes, snails, and surrogates.
The high-resolution structure of a synthetic 13-residue peptide in a tight complex with alpha-bungarotoxin conforms to the beta hairpin structure of a closely related segment in the ACh binding protein and reveals how the ACh binding protein and the homologous nicotinic ACh receptors bind alpha-bungarotoxin at their ACh binding sites.
