Scorpion Toxins

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1997
Scorpion are known to use a cocktail of toxins to immobilize their prey. So, their venoms constitute a complex mixture of polypeptides exhibiting different pharmacological activities. These polypeptides are small (between 30 and 70 amino acids long), basic and highly reticulated (3 or 4 disulfide bridges).

SCORPION, a molecular database of scorpion toxins

Toxicon, 2002
Increasing interest in the studies of toxins and the requirements for better structural and functional annotations have created a need for improved data management in the field of toxins. The molecular database, SCORPION, contains more than 200 entries of fully referenced scorpion toxin data including primary sequences, three-dimensional structures ...

Scorpion toxins prefer salt solutions

Journal of Molecular Modeling, 2015
There is a wide variety of ion channel types with various types of blockers, making research in this field very complicated. To reduce this complexity, it is essential to study ion channels and their blockers independently. Scorpion toxins, a major class of blockers, are charged short peptides with high affinities for potassium channels.

Conformational variations amongst scorpion toxins

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1986
Circular dichroism spectra were obtained for ten scorpion neurotoxins (representing five species of scorpion) in order to provide an understanding of their relative conformations in solution. Despite a high degree of amino acid sequence homology, the toxins clearly differ from each other in terms of CD-detectable structure.

Scorpion Toxin Polyptides as Therapeutic Agents: An Overview.

Protein & Peptide Letters, 2016
Scorpions are distributed throughout the world and numerous biological molecules are found in their venom most importantly peptide toxins. These toxins modulate the ion channels either by blocking the pore of the channel or by altering the voltage gating. Molecules which block the pores have been useful in deciphering the structure of the ion channels.

Radioiodination of scorpion and snake toxins

Analytical Biochemistry, 1977
Abstract Several scorpion and snake toxins were radioiodinated using the lactoperoxydase method of [125I]iodide oxidation. Two techniques of labeling were set up: (i) Using carrier-free Na125I and 5 μg of toxin, about one iodine atom was incorporated per mole of protein without loss of toxicity.
