Nucleotide pool-sensitive selection of the transcriptional start site in vivo at the Salmonella typhimurium pyrC and pyrD promoters.

Expression of the Salmonella typhimurium pyrC and pyrD genes is regulated in response to fluctuations in the intracellular CTP/GTP pool ratio. The repressive mechanism involves the formation of a stable secondary structure (hairpin) at the 5' ends of the transcripts that precludes translational init...
