01/01/1986 - "It is concluded that enzyme activity is important for the presynaptic effects of caudoxin, but not for the contracture-inducing action of the Naja nigricollis enzyme. "
01/01/1986 - "In the chick muscle pretreated with heparin, the latter enzyme fails to evoke contracture, whereas the presynaptic neuromuscular blocking action of caudoxin remains little affected. "
01/01/1986 - "Reducing catalytic activity by lowering the incubation temperature or by substitution of Sr2+ for Ca2+ in the bathing medium causes a significant prolongation of the time to neuromuscular block by caudoxin, but does not change the contracture-inducing activity of Naja nigricollis basic phospholipase A2. "
01/01/1986 - "Two toxic phospholipases A2, caudoxin from Bitis caudalis venom and the basic phospholipase A2 from Naja nigricollis venom, were selected for a study of the contribution of enzyme activity and charge properties to the presynaptic neurotoxicity and the contracture-inducing activity of the enzyme.
