Abstract: The transcriptional activator RtcR and the RNA repair proteins whose expression it regulates, RtcA and RtcB, are widely conserved in Proteobacteria. In Salmonella Typhimurium 14028s, genotoxic stress activates RtcR to direct RpoN-dependent expression of the… read more here.

Abstract: Transfer RNA fragments are proposed to regulate numerous processes in eukaryotes, including translation inhibition, epigenetic inheritance, and cancer. In the bacterium Salmonella enterica serovar Typhimurium, 5′ tRNA halves ending in 2′,3′ cyclic phosphate are proposed… read more here.
