Calcium ion independent membrane leakage induced by phospholipase-like myotoxins
(1992-12)The two snake venom myotoxins ammodytin L and myotoxin II, purified respectively from Vipera ammodytes ammodytes and Bothrops asper, have phospholipase-like structures but lack an Asp-49 in the active site and are without ... -
Effect of Bothrops asper (Fer-De-Lance) snake venom on erythrocyte membrane. A comparative study
(1992-02)1. The effect of Bothrops asper venom on erythrocytes of different species, sheep erythrocyte ghost vesicles and liposomes made of phospholipids from sheep erythrocytes was studied. 2. B. asper venom had a direct hemolytic ... -
Myonecrosis induced in mice by a basic myotoxin isolated from the venom of the snake Bothrops nummifer (jumping viper) from Costa Rica
(1989)The mode of action of a basic myotoxin isolated from Bothrops nummifer venom was studied. This myotoxin is a basic polypeptide of 13,000 mol.wt, with a high content of lysine and aspartate, as well as of hydrophobic amino ... -
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 ... -
Structure of a calcium-independent phospholipase-like myotoxic protein from Bothrops asper venom
(1995-05-01)Myotoxin II, a myotoxic calcium-independent phospholipase-like protein isolated from the venom of Bothrops asper, possesses no detectable phospholipase activity. The crystal structure has been determined and refined at 2.8 ... -
The C-terminal region of a Lys49 myotoxin mediates Ca2þ influx in C2C12 myotubes
(2010-02)Myotoxins are abundant components of snake venoms, being a significant public health problem worldwide. Among them, Lys49 phospholipase A2 homologue myotoxins cause extensive necrosis in skeletal muscle tissue. Their ... -
The effect of myotoxins isolated from Bothrops snake venoms on multilamellar liposomes: relationship to phospholipase A2, anticoagulant and myotoxic activities
(1991-12)The effect of four myotoxins isolated from Bothrops snake venoms on the release of peroxidase trapped in large multilamellar liposomes was studied and correlated to their phospholipase A2, myotoxic and anticoagulant ...
