| Abstract: | The aminoacylation of tRNA was investigated with respect to protein synthesis in the rat liver. No correlation was found between the 85-90% inhibition of protein synthesis 2 h after cycloheximide injection and aminoacylation level of some tRNAs both in vivo and in vitro. A decrease in aminoacylation (28%) was established only for lysine. During the recovery phase of protein synthesis 12 and 24 h after cycloheximide treatment the aminoacylation maximal level of mixture with 14C amino acids, 14C leucine, 14C glutamic acid was unchanged. |
