Snake Venom Toxins
نویسنده
چکیده
A toxin, designated Fvrr has been isolated from the venom of the green mamba Dendroaspis angusticeps by ion exchange chromatography on Amberlite CG-50 and gel filtration on Sephadex G-50. . Toxin FvII consists of 61 amino acid residues, is devoid of phenylalanine and tryptophan, and is cross-linked by four intramolecular disulfide bridges. Immunochemically, toxin FvII is completely distinct from the 61 and 71 amino acid residue neurotoxins and also from the cardiotoxins. The amino acid sequence of toxin Fvrr reveals homology with the neuroand cardiotoxins.

Computational Studies of Snake Venom Toxins
Most snake venom toxins are proteins, and participate to envenomation through a diverse array of bioactivities, such as bleeding, inflammation, and pain, cytotoxic, cardiotoxic or neurotoxic effects. The venom of a single snake species contains hundreds of toxins, and the venoms of the 725 species of venomous snakes represent a large pool of potentially bioactive proteins. Despite considerable ...
متن کاملSnake Venom Cytotoxins, Phospholipase A2s, and Zn2+-dependent Metalloproteinases: Mechanisms of Action and Pharmacological Relevance
Snake venom toxins are responsible for causing severe pathology and toxicity following envenomation including necrosis, apoptosis, neurotoxicity, myotoxicity, cardiotoxicity, profuse hemorrhage, and disruption of blood homeostasis. Clinically, snake venom toxins therefore represent a significant hazard to snakebite victims which underscores the need to produce more efficient anti-venom. Some sn...
متن کاملInhibition of Hemorragic Snake Venom Components: Old and New Approaches
Snake venoms are complex toxin mixtures. Viperidae and Crotalidae venoms, which are hemotoxic, are responsible for most of the envenomations around the world. Administration of antivenins aimed at the neutralization of toxins in humans is prone to potential risks. Neutralization of snake venom toxins has been achieved through different approaches: plant extracts have been utilized in etnomedici...
متن کاملAssembling an arsenal: origin and evolution of the snake venom proteome inferred from phylogenetic analysis of toxin sequences.
We analyzed the origin and evolution of snake venom toxin families represented in both viperid and elapid snakes by means of phylogenetic analysis of the amino acid sequences of the toxins and related nonvenom proteins. Out of eight toxin families analyzed, five provided clear evidence of recruitment into the snake venom proteome before the diversification of the advanced snakes (Kunitz-type pr...
متن کاملVenom-Related Transcripts from Bothrops jararaca Tissues Provide Novel Molecular Insights into the Production and Evolution of Snake Venom
Attempts to reconstruct the evolutionary history of snake toxins in the context of their co-option to the venom gland rarely account for nonvenom snake genes that are paralogous to toxins, and which therefore represent important connectors to ancestral genes. In order to reevaluate this process, we conducted a comparative transcriptomic survey on body tissues from a venomous snake. A nonredunda...
متن کاملRestriction and Recruitment—Gene Duplication and the Origin and Evolution of Snake Venom Toxins
Snake venom has been hypothesized to have originated and diversified through a process that involves duplication of genes encoding body proteins with subsequent recruitment of the copy to the venom gland, where natural selection acts to develop or increase toxicity. However, gene duplication is known to be a rare event in vertebrate genomes, and the recruitment of duplicated genes to a novel ex...
