Abstract excerpt
We previously showed that: (i) E.coli threonyl-tRNA synthetase (ThrRS) binds to the leader of its mRNA and represses translation by preventing ribosome binding to its loading site; (ii) the translational operator shares sequence and structure similarities with tRNA(Thr); (iii) it is possible to switch the specificity of the translational control from ThrRS to methionyl-tRNA synthetase (MetRS) by changing the CGU...
