Following this discovery, a variety of neurotoxins were characterized and their amino acids sequences, secondary structure and tertiary structure were also characterized. These toxins are polypeptides of single chain and consist of 46-49 amino acids, cross-linked by three disulfide bridges. The ordered secondary structure has been determined on the basis of NMR studies. The dominant feature is a four-stranded anti-parallel β-sheet, linked with three loop.
