An electrophoretic study on phospholipase A2 isoenzymes in the venoms of Central American crotaline snakes
The number and isoelectric points of phospholipase A2 isoenzymes were studied in the venoms of 12 Central American crotaline snakes of the genera Bothrops, Crotalus, Lachesis and Agkistrodon. The study was carried out by ...
Synthetic peptides derived from the C-terminal region of Lys49 phospholipase A2 homologues from Viperidae snake venoms: biomimetic activities and potential applications
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 ...
Tyr→Trp-substituted peptide 115-129 of a Lys49 phospholipase A2 expresses enhanced membrane-damaging activities and reproduces its in vivo myotoxic effect
Myotoxin II is a group II Lys49 phospholipase A2 (PLA2) isolated from the venom of the snake Bothrops asper. Previous studies on a synthetic peptide derived from its heparin-binding, cationic/hydrophobic sequence 115^129 ...
Depletion of complement enhances the clearance of Brucella abortus in mice
Brucellosis is a bacterial disease of animals and humans. Brucella abortus barely activates the innate immune system at the onset of infection, and this bacterium is resistant to the microbicidal action of complement. ...
Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ...
