The fidelity of tRNA aminoacylation is a critical determinant for the ultimate accuracy of protein synthesis. Although aminoacyl-tRNA synthetases are assumed to consistently maintain high tRNA charging fidelity, recent evidence has demonstrated that the fidelity of the aminoacylation reaction can be actively regulated and liable to change. Accordingly, the ability to conveniently assay the fidelity...
Though up to 20% of the total RNA in bacterial cells is tRNA, the regulation of tRNA distribution on the genomic level remains unclear. tRNA distribution is governed by four processes: transcription, processing of precursor tRNA, degradation of precursor tRNA and degradation of mature tRNA. To elucidate the relationship between these processes in the regulation of tRNA production, the relative tRNA...
