abstract：:The rate of in vivo transcription from the E. coli tRNA and rRNA promoters depends on both cellular growth rate and aminoacid availability. To investigate the molecular mechanisms involved we determined the extent of interaction of RNA polymerase with the promoter of the tyrT stable RNA gene. We show that the enzyme c...
