Abstract

A tRNA(Lys)-specific anticodon nuclease is kept in a latent form in a rare Escherichia coli strain, complexed with a DNA restriction enzyme. A phage T4 inhibitor of DNA restriction activates anticodon nuclease, but other T4 proteins restore tRNA(Lys). Detection of a homologous system in Neisseria and a different anticodon nuclease in colicin E5 suggest ubiquity and diversity of such tRNA toxins. Analysis of these systems could reveal novel RNA recognition and cleavage mechanisms.
