Abstract: | Cadmium ions are studied for their effect on the reaction rate of tRNA aminoacylation which was carried out using overall preparations of aminoacyl-tRNA-synthetases (ARSases) isolated from muscles of male rabbits and from three-day pea seedling roots. Cadmium in the concentration of 3 X 10(-5) M is established to accelerate the reaction rate two times as compared to the norm. Other bivalent cations of metals lack this ability. |
