Studies on Snake Venom*

Abstract
Proteinase activity (substrate; casein or azocoll) was present only in venoms of Crotalidae, while peptidase activity was detected in venoms of Elapidae, especially of B. multicinetus. Esterase activities towards alpha-benzoyl-L-arginine ethyl ester and alpha-acetyl-L-tyrosine ethyl ester were distributed along with proteinase activity, but this was not the case with esterase activities for p-nitrophenyl acetate, [beta]-naphthyl acetate and acetylcholine.
