In vivo analysis of the mechanisms responsible for strong transcriptional polarity in a "sense" mutant within an intercistronic region.

We have studied a very unusual strong polar mutant in the intercistronic barrier between the second (hisD) and third (hisC) cistrons of the histidine operon of Salmonella typhimurium to obtain further insights into the molecular mechanisms leading to transcription termination within cistrons. We have performed a detailed transcriptional analysis in vivo and have found that the his mRNA in this polar mutant is reduced in size as a result of premature termination of transcription at a cryptic Rho-dependent site within the proximal region of the hisC cistron.[1]
