Conformational heterogeneity in the Salmonella typhimurium pyrC and pyrD leader mRNAs produced in vivo.

In Salmonella typhimurium, different conformations of the pyrC and pyrD leader transcripts are produced as a result of nucleotide sensitive selection of the transcriptional start site. The CTP-initiated transcripts, synthesized at high intracellular CTP/GTP pool ratios (repressing conditions), have...
