Characterization of Ribonucleic Acids from the Venom Glands of Crotalus durissus terrificus (Ophidia, Reptilia) after Manual Extraction of the Venom
RNA synthesis in the venom glands of Crotalus durissus terrificus was stimulated by the manual extraction of the venom (milking). RNA was extracted from venom glands activated by milking and fractionated by centrifugation through sucrose density gradients. Template activity for protein synthesis and base composition of the RNA fractions were studied. RNA fractions that sediment between 18S and ...
متن کاملAge-dependent variations in the venom proteins of Vipera xanthina (Gray, 1849) (Ophidia: Viperidae).
In this study, polyacrylamide disc gel electrophoresis and densitometry analysis methods were used to analyze venom extracts of Vipera xanthina specimens of different lengths (35, 47 and 88 cm) collected from the same locality. The electropherograms of the venom protein samples showed age-dependent qualitative and quantitative variations.
متن کاملVipera palaestinae snake envenomations: experience in children.
In Israel, Vipera palaestinae (V. palaestinae) is the most common venomous snake, accounting for 100-300 reported cases of envenomation every year. However, V. palaestinae snakebites in children have not been extensively investigated. The demographic features, treatment and outcome of V. palaestinae envenomation in 37 children treated in two medical centers over a 9 year period were retrospecti...
متن کاملStudies on Soluble Ribonucleic Acid: the Action of Snake Venom Phosphodiesterase on Soluble Ribonucleic Acid in Yeast.
Useful information on the structure of soluble ribonucleic acid may be obtained by a study of the action of snake venom diesterase on it, to the extent that the mechanism of action of the enzyme itself is understood. Snake venom phosphodiesterase has been widely studied and extensively purified (l-5). Two basic conclusions have been reached as to its mechanism of action on ribonucleotide and de...
متن کاملStudies on Termination of in Vitro Ribonucleic Acid Synthesis
The mechanism of action of the protein rho (p) in DNAdependent RNA synthesis has been examined. While p can interact with DNA to form a protein-DNA complex, detailed studies of this interaction suggest that this is not the mode of action of p. p appears to interact with Escherichia coli RNA polymerase at specific DNA sites leading to the formation of RNA chains of well defined length. RNA chain...
