Amino acid sequence of toxin VII, a beta-toxin from the venom of the scorpion Tityus serrulatus.
The sequence of the 61 amino acids of toxin VII, a beta-toxin from the venom of the South American scorpion Tityus serrulatus, has been determined by automatic sequencing of the reduced and S-[14C] carboxymethylated protein and of tryptic peptides obtained before or after citraconylation of this protein. This toxin, the most active beta-toxin from this venom, is the first Tityus toxin to be fully sequenced. The results clearly show that toxin VII belongs to the structural group of scorpion toxins originating from Central and North America.
