The influence of various salts on the aminoacylation of tRNA(Val) and the tRNA-like structure from turnip yellow mosaic virus RNA by yeast valyl-tRNA synthetase has been studied. As expected, increasing the concentration of salts inhibits the enzymatic reaction. However, in the presence of high concentration of ammonium sulfate, and only this salt, the inhibitory effect is suppressed. Under such conditions, the aminoacylation becomes comparable to that measured in the absence of salt. It was shown that ammonium sulfate affects both the catalytic rate of the reaction and the affinity between valyl-tRNA synthetase and the RNAs. Because the affinity between the partners in the complex is increased when the concentration of the salt is high, it is suggested that hydrophobic effects are involved in tRNA/synthetase interactions.
