WebCrotalus durissus terrificus (C.d.t.) (South American rattlesnake) venom possesses myotoxic and neurotoxic activities, both of which are also expressed by crotoxin, the principal toxin of this venom. Crotoxin contains a basic phospholipase A2 (PLA2) The toxin has phospholipase C activity, and causes hemolysis, lethality, and dermonecrosis. At high concentrations, alpha-toxin induces massive degradation of phosphatidylcholine and sphingomyelin, producing diacylglycerol and ceramide, respectively. These molecules then participate in signal … See more Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group (see figure).
