Myotoxin II from Bothrops asper (Terciopelo) venom is a lysine-49 phospholipase A2
(1991)
A basic, dimeric myotoxic protein, myotoxin II, purified from Bothrops asper venom has a similar molecular weight and is immunologically cross-reactive with antibodies raised to previously isolated B. asper phospholipases ...
Danger in the reef: Proteome, toxicity, and neutralization of the venom of the olive sea snake, Aipysurus laevis
(2015-12-01)
Four specimens of the olive sea snake, Aipysurus laevis, were collected off the coast of Western Australia, and the venom proteome was characterized and quantitatively estimated by RP-HPLC, SDS-PAGE, and MALDI-TOF-TOF ...
Cardiac effect induced by Crotalus durissus cascavella venom: morphofunctional evidence and mechanism of action
(2021)
Envenoming, resulting from snake bites, is a global public health problem. The present study was undertaken to investigate the influence of Crotalus durissus cascavella (Cdcas) venom on cardiac activity and the mechanisms ...
An overview of Lysine-49 phospholipase A2 myotoxins from crotalid snake venoms and their structural determinants of myotoxic action
(2003)
In 1984, the first venom phospholipase A2 (PLA2) with a lysine substituting for the highly conserved aspartate 49 was
discovered, in the North American crotalid snake Agkistrodon p. piscivorus [J. Biol. Chem. 259 (1984) ...
Screening for target toxins of the antiophidic protein DM64 through a gel-based interactomics approach
(2017-01)
DM64 is a glycosylated protein with antivenomactivity isolated fromthe serum of the opossumDidelphis aurita.
It binds non-covalently to myotoxins I (Asp49) and II (Lys49) from Bothrops asper venom and inhibits their
myotoxic ...
Preadipocytes are target cells for the actions of a representative gIIA phospholipase A2 which triggers proinflammatory pathways related to obesity
(2020)
Adipose tissue secretes proinflammatory mediators which promote systemic and adipose tissue inflammation seen in obesity. Group IIA (GIIA)-secreted phospholipase A2 (sPLA2) enzymes are found to be elevated in plasma and ...
Synthetic peptides derived from the C-terminal region of Lys49 phospholipase A2 homologues from Viperidae snake venoms: biomimetic activities and potential applications
(2010)
Lys49-phospholipase A2 homologues constitute a large family of toxins present in the venoms of viperid snake species, which
despite lacking catalytic activity, cause significant skeletal muscle necrosis. The main structural ...
Implementación de un laboratorio de análisis proteómicos en el Instituto Clodomiro Picado (UCR): primeras experiencias en Costa Rica
(2012)
Reseña sobre avances tecnológicos en la implementación de un laboratorio de análisis proteómico en Costa Rica. Se describe la espectrometría de masas, la ionización de muestra, la instrumentación básica, la espectrometría ...
Cytotoxicity of Lachesis muta muta snake (bushmaster) venom and its purified basic phospholipase A2 (LmTX-I) in cultured cells
(2007)
Human envenoming by Lachesis muta muta venom, although infrequent, is rather severe, being characterized by
pronounced local tissue damage and systemic dysfunctions. Studies on the pharmacological actions of L. m. muta ...
Integrative characterization of the venom of the coral snake Micrurus dumerilii (Elapidae) from Colombia: proteome, toxicity, and cross-neutralization by antivenom
(2016-03)
In Colombia, nearly 2.8% of the 4200 snakebite accidents recorded annually are inflicted by coral snakes (genus
Micrurus). Micrurus dumerilii has a broad distribution in this country, especially in densely populated ...
