Neurotoxins from Clostridium botulinum (serotype A) isolated from the soil of Mendoza (Argentina) differ from the A-Hall archetype and from that causing infant botulism
(Pergamon-Elsevier Science Ltd, 2016-10)
The type A of neurotoxin produced by Clostridium botulinum is the prevalent serotype in strains of Mendoza. The soil is the main reservoir for C.botulinum and is possibly one of the infection sources in infant botulism. ...
Antibody-mediated neutralization and binding-reversal studies on α-neurotoxins from micrurus nigrocinctus nigrocinctus (coral snake) venom
(1996-03)
An ELISA based, non-radioactive acetylcholine receptor (AchR) binding assay was used to detect the alpha-neurotoxins present in Micrurus nigrocinctus nigrocinctus venom. Sera from horses hyperimmunized against M. nigrocinctus ...
Investigation of the relationship between the structure and function of Ts2, a neurotoxin from Tityus serrulatus venom
(WILEY-BLACKWELLMALDEN, 2012-04)
Scorpion toxins targeting voltage-gated sodium (NaV) channels are peptides that comprise 6076 amino acid residues cross-linked by four disulfide bridges. These toxins can be divided in two groups (a and beta toxins), ...
Crystal structure of bucain, a three-fingered toxin from the venom of the Malayan krait (Bungarus candidus)
(2009-12-01)
Bucain, a potent neurotoxin isolated from the venom of the Malayan krait (Bungarus candidus), induces paralysis and death. Its crystal structure has been determined at 2.10 Å resolution and based on the molecular topology ...
Cellular pathology induced by snake venom phospholipase A2 myotoxins and neurotoxins: common aspects of their mechanisms of action
(2008-06-20)
A large variety of snake toxins evolved from PLA2 digestive enzymes through a process of ‘accelerated evolution’. These toxins have different tissue targets, membrane receptors and mechanisms of alteration of the cell ...
Highly Toxic Microcystis aeruginosa Strain, Isolated from So Paulo-Brazil, Produce Hepatotoxins and Paralytic Shellfish Poison Neurotoxins
(SPRINGER, 2011)
While evaluating several laboratory-cultured cyanobacteria strains for the presence of paralytic shellfish poison neurotoxins, the hydrophilic extract of Microcystis aeruginosa strain SPC777-isolated from Billings`s ...
Characterization of alpha-neurotoxin and phospholipase A2 activities from Micrurus venoms. Determination of the amino acid sequence and receptor-binding ability of the major alpha-neurotoxin from Micrurus nigrocinctus nigrocinctus
(1996)
New World elapids are coral snakes that belong to the genus Micrurus, and for which the venom biochemistry is mostly unknown. Analysis has been difficult because the coral snakes produce small quantities of venom. Clinical ...
The neuromuscular activity of paradoxin: A presynaptic neurotoxin from the venom of the inland taipan (Oxyuranus microlepidotus)
(Pergamon-elsevier Science LtdOxfordInglaterra, 2007)
Crystal structure of neurotoxin Ts1 from Tityus serrulatus provides insights into the specificity and toxicity of scorpion toxins
(Academic Press LtdLondonInglaterra, 1999)
