Transcription of ribosomal genes during a nutritional shift-up of Escherichia coli.
We measured the differential transcription rates of individual ribosomal operons after a nutritional shift-up. All operons showed a transient increase in transcription. However, the response of the S10 ribosomal protein operon was much stronger than that of any other operon. We propose that only the S10 operon is autogenously regulated by a transcription attenuation mechanism.
