WebAug 1, 1984 · Half-lives of tRNA and the initial rates of tRNA accumulation are correlated with the growth rates of cell suspension cultures of Lupinus angustifolius cv. Turkus and Petroselinum hortense cv. Berlinska.. Half-lives of tRNA are approximately proportional to the doubling times of cells in these cultures. WebApr 12, 2024 · Chemical modifications of tRNA (tRNA modifications) are found in all kingdoms of life and fine-tune tRNA properties including mRNA decoding efficiency, recognition by aminoacyl-tRNA synthetases, half-life and structural stability[, -].

WebDec 8, 2024 · An inadequate supply of amino acids leads to accumulation of uncharged tRNAs, which can bind and activate GCN2 kinase to reduce translation. Here, we show that glutamine-specific tRNAs selectively become uncharged when extracellular amino acid availability is compromised. WebJul 15, 2002 · A wide range of stabilities was observed for individual mRNAs of E. coli, although ≈80% of all mRNAs had half-lives between 3 and 8 min. Genes having biologically related metabolic functions were commonly observed to have similar stabilities.
