Dual transcriptional initiation sites from the pyrC promoter control expression of the gene in Salmonella typhimurium.

Molecular & general genetics : MGG - 1 Feb 1991

Sørensen K I, Neuhard J

Abstract excerpt

Expression of the Salmonella typhimurium pyrC gene encoding dihydroorotase is negatively regulated by CTP and stimulated by GTP. This regulation does not occur at the level of transcription initiation but appears to involve translation attenuation of the transcripts. Alterations of specific bases in a region of hyphenated dyad symmetry located in the leader established that base pairing in the 5' terminal region...
