Gene structures of S. catenatus edwardsii three-finger toxins. A) Strategy used in determining the gene structures. B) Schematic representation of the gene structures of three-finger toxins. The exon-intron boundaries were determined by comparison with the cDNA sequences. Exons are represented by boxes and introns are represented by solid line. The number of base pairs in the introns and total length are also shown.
