LITERATURE
cells expressing the native trmD show more than a 6fold activation of transcription upon switching from high to low Mg2+ media, whereas cells expressing a S88L mutant trmD show less than a 2fold activation. For cells expressing the native trmD, the level of Mg2+ modulates the level of TrmD-dependent m1G37-tRNA synthesis, which in turn modulates the speed of ribosomal translation of m1G37-dependent codons in the 5'-leader ORF. At high Mg2+, TrmD is active and the abundantly synthesized m1G37-tRNA facilitates ribosomal translation through the 5'-leader ORF
