Abstract

The Escherichia coli ygjD gene is critical for the universal tRNA modification N(6)-threonylcarbamoyladenosine, together with two other essential genes, yeaZ and yjeE. This study showed that the transcription of the thr and ilv operons in ygjD mutants was increased through the inhibition of transcription attenuation and that dnaG transcription was reduced.
