Journal ArticleDOI
Proteomic analysis of the venom from the scorpion Tityus stigmurus: Biochemical and physiological comparison with other Tityus species ☆
Cesar Vicente Ferreira Batista,Sergio A. Román-González,Saida Patricia Salas-Castillo,Fernando Z. Zamudio,Froylan Gómez-Lagunas,Lourival D. Possani +5 more
TL;DR: A correlation among HPLC retention times and molecular masses of folded scorpion toxins as well as a comparative structural and physiological analysis of components from the venom of several species of the genus Tityus are reported.
Journal ArticleDOI
Proteomics of the venom from the Amazonian scorpion Tityus cambridgei and the role of prolines on mass spectrometry analysis of toxins.
Cesar Vicente Ferreira Batista,Luis del Pozo,Fernando Z. Zamudio,Sandra Contreras,Baltazar Becerril,Enzo Wanke,Enzo Wanke,Lourival D. Possani +7 more
TL;DR: The thermo-instability of scorpion toxins subjected to electron spray ionization-mass spectrometry (ESI-MS) is shown and when a proline residue is located near the N-terminal region of the toxin, artificial components are generated by the mass spectrometer conditions, due to the cleavage of the peptide bond at the proline positions.
Journal ArticleDOI
The Brazilian scorpion Tityus costatus Karsch: genes, peptides and function.
Elia Diego-García,Cesar Vicente Ferreira Batista,Blanca I. García-Gómez,Sylvia M. Lucas,Denise Maria Candido,Froylan Gómez-Lagunas,Lourival D. Possani +6 more
TL;DR: Stings by scorpions of the species Tityus costatus should be taken with caution by medical doctors, and some of these peptides and genes are similar to other known scorpion toxins.
Journal ArticleDOI
Proteomic analysis of Tityus discrepans scorpion venom and amino acid sequence of novel toxins
Cesar Vicente Ferreira Batista,Gina D'Suze,Gina D'Suze,Froylan Gómez-Lagunas,Fernando Z. Zamudio,Sergio Encarnación,Carlos Sevcik,Carlos Sevcik,Lourival D. Possani +8 more
TL;DR: Comparative analysis of the amino acid sequences found suggests that this venom contains peptides highly similar to those that block K+ channels, as well as those that modify the gating mechanisms of Na+annels, found in other scorpions.
Journal ArticleDOI
Two novel toxins from the Amazonian scorpion Tityus cambridgei that block Kv1.3 and Shaker B K+-channels with distinctly different affinities
Cesar Vicente Ferreira Batista,Froylan Gómez-Lagunas,Ricardo C. Rodríguez de la Vega,Péter Hajdu,Gyorgy Panyi,Rezsö Gáspár,Lourival D. Possani +6 more
TL;DR: Two novel toxic peptides were isolated and characterized from the venom of the Brazilian scorpion Tityus cambridgei, one of which was classified as the first example of a new subfamily of K(+)-channel-specific peptides.
