Structural and functional comparison of toxins from the venom of the scorpions Centruroides infamatus infamatus, centruroides limpidus limpidus and Centruroides noxius [PDF]
Comparative Biochemistry and Physiology - B Biochemistry and Molecular Biology, 1996 Two novel toxins containing 66 amino acid residues each were isolated from the venom of the scorpions Centruroides infamatus infamatus and Centruroides limpidus limpidus, respectively. Their full amino acid sequences were determined. Comparison of primary structures showed that they share 97% similarity among themselves and 83% to that of toxin 2 from ...

Biochemistry, 1994 A crustacean-specific toxin from the Mexican scorpion Centruroides limpidus limpidus was purified, and its primary sequence was determined, including disulfide bonds. This toxin has 66 amino acid residues and is stabilized by four disulfide bridges (Cys12-Cys65, Cys16-Cys41, Cys25-Cys46, and Cys29-Cys48). A detailed nuclear magnetic resonance structure

Toxicon, 1994
A novel peptide, toxic to mice, was purified from the venom of the Mexican scorpion Centruroides limpidus limpidus, by means of gel filtration and ion exchange chromatography, followed by high performance liquid chromatography (HPLC). The complete amino acid sequence was determined by automatic Edman degradation of reduced and alkylated toxin, and by ...

Mortality rates of mice and their levels of anti-venom and anti-F(ab')2 antibodies were assessed after three episodes of subcutaneous envenomations with or without treatment with horse F(ab')2. Soluble venom from the Mexican scorpion Centruroides limpidus limpidus was used for these experiments. Repetition of episodes did not induce different mortality

A large number of novel Ergtoxin-like genes and ERG K+ -channels blocking peptides from scorpions of the genus Centruroides [PDF]
FEBS Letters, 2002 Twenty-three novel sequences similar to Ergtoxin (ErgTx) were obtained by direct sequencing of peptides or deduced from gene cloned using cDNAs of venomous glands of Centruroides (C.) elegans, C. exilicauda, C. gracilis, C. limpidus limpidus, C.

1. Several toxic polypeptides were found in the venom of the scorpion Centruroides limpidus limpidus. Comparative studies of the potency of the venom in different strains of mice were conducted. 2. A new type of toxin (component II.9), specific for crustaceans (crayfish and isopods), was isolated from this scorpion and was shown to have the following N-

Lidocaine As Antagonist of Scorpion Poison Toxicity from Centruroides limpidus limpidus
Archives of Medical Research, 2001In Mexico, scorpion poisoning is a health problem because the poison has beta toxins that affect sodium channel activation. Lidocaine decreases ion permeability across the sodium channel acting in the opposite manner. The aim of this work is to determine whether lidocaine antagonized the toxic effect of the crude poison of Centruroides limpidus ...
