Amino acid sequence of versutoxin, a lethal neurotoxin from the venom of the funnel-web spider Atrax versutus.


ABSTRACT: The complete amino acid sequence of versutoxin, a lethal neurotoxic polypeptide isolated from the venom of male and female funnel-web spiders of the species Atrax versutus, was determined. Sequencing was performed in a gas-phase protein sequencer by automated Edman degradation of the S-carboxymethylated toxin and fragments of it produced by reaction with CNBr. Versutoxin consisted of a single chain of 42 amino acid residues. It was found to have a high proportion of basic residues and of cystine. The primary structure showed marked homology with that of robustoxin, a novel neurotoxin recently isolated from the venom of another funnel-web-spider species, Atrax robustus.
