Biochemical and Structural Studies of RNA Modification and Repair
… not only repairs tRNAAsp and tRNAArg cleaved by ribotoxins colicin E5 and colicin D, respectively, but also adds a methyl group to the same 2'OH group, which acts as a nucleophile during RNA cleavage by the ribotoxins. As a result, the repaired tRNAs resist the re-attack by ribotoxins. This …

Biochemical and structural studies of RNA damage and repair in bacteria
… own survival and growth. Many organisms utilize ribotoxins to respond to cellular stress or to kill competing organisms. Ribotoxins are site-specific endonucleases which typically target RNA molecules that are necessary for translation mainly, tRNAs and rRNAs which can result in their loss of …

Biochemical and Structures Studies of tRNA Modificaton and Repair Enzymes
… Pnkp/Hen1 could not be cleaved again by the ribotoxins. Thus, unlike eukaryotic Hen1 involved in RNAi, bacterial Hen1 is part of a RNA repair and modification system.
