Hydrolysis of tRNA^Phe on Suspensions of Amino Acids

RNA is adsorbed strongly on suspensions of many moderately soluble organic solids. In some cases, the hydrolysis of tRNA^Phe is greatly accelerated by adsorption, and the major sites of hydrolysis are changed from those that are important in homogeneous solution. Here we show that the hydrolysis is greatly accelerated by suspensions of aspartic acid and β-glutamic acid but not by suspensions of α-glutamic acid, asparagine, or glutamine.
