Effects on Transcription of Mutations in ygjD, yeaZ, and yjeE Genes, Which Are Involved in a Universal tRNA Modification in Escherichia coli

摘要

The Escherichia coli ygjD gene is critical for the universal tRNA modification N6-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.
