Inactivation of PTH (peptidyl-tRNA hydrolase) causes rapid accumulation of pep-tRNAs and depletion of aminoacyl(aa)-tRNAs, leading to defective protein synthesis. We established a highly sensitive method for direct profiling of pep-tRNAs accumulated in the cell and identified more than 700 peptide sequences of the pep-tRNAs. In this experiment, to examine the involvement of RRF in pep-tRNA drop-off in the early elongation stage, we performed ribosome profiling of WT and temperature-sensitive RRF strain incubated at 43°C for 30 min.pathogen:prioritypathogen:bacteriumpathogenbacteriaENAfalseEscherichia coli BW25113Ribosome profiling analyses on WT and RRFTs strain2025-09-242023-05-21PRJDB12336679895
