Abstract

X-irradiation of animals with an absolutely lethal dose of 0.21 C/kg increases the incorporation of a methyl group into aminoacyl-tRNA-synthetases the radioactive label being traced in lysine, arginine, and histidine. The isolated protein methyltransferase methylated total preparations of aminoacyl-tRNA-synthetases and lysyl-tRNA-synthetase of rat liver in the in vitro experiments with the use of S-adenosylmethionine-14CH3 as a donor of methyl groups: the radioactive label was traced in arginine, lysine, histidine, aspartic and glutamic acids.
