E. coli and human tRNAs contain 3-(3-amino-3-carboxypropyl)uridine (acp3U) modification. Here the authors identify E. coli TapT and human DTWD1/2 as tRNA aminocarboxypropyltransferases responsible for acp3U formation. Inhibition of acp3U modification results in genome instability in heat-stressed E. coli and growth defects in human cells.
