TranscriptomicsNascent elongating transcript sequencing (NET-seq) for Escherichia coli and Bacillus subtilis reveals a consensus pause sequence enriched at translation start sites.
Transcription by RNA polymerase (RNAP) is interrupted by pauses that play diverse regulatory roles. Although individual pauses have been studied in vitro, the determinants of pauses in vivo and their distribution throughout the bacterial genome remain unknown. Using nascent transcript sequencing we ...

TranscriptomicsRho directs widespread termination of intragenic and stable RNA transcription
The transcription termination factor Rho is a global regulator of RNA polymerase (RNAP). Although individual Rho-dependent terminators have been studied extensively, less is known about the sites of RNAP regulation by Rho on a genome-wide scale. Using chromatin immunoprecipitation and microarrays (...

TranscriptomicsRegulator trafficking on bacterial transcription units in vivo
The in vivo trafficking patterns on DNA by the bacterial regulators of transcript elongation Sigma70, Rho, NusA, and NusG and the explanation for high promoter-proximal levels or peaks of RNA polymerase (RNAP) are unknown. Genome-wide ChIP-chip on E. coli revealed distinct association patterns of r...

TranscriptomicsDksA Guards Elongating RNA Polymerase Against Ribosome-Stalling-Induced Arrest
In bacteria, translation-transcription coupling inhibits RNA polymerase (RNAP) stalling. We present evidence suggesting that, upon amino acid starvation, inactive ribosomes promote rather than inhibit RNAP stalling. We developed an algorithm to evaluate genome-wide polymerase progression independent...

TranscriptomicsRho and NusG suppress pervasive antisense transcription in Escherichia coli [RNA-seq].
Despite the prevalence of antisense transcripts in bacterial transcriptomes, little is known about how their synthesis is controlled. We report that a major function of the Escherichia coli termination factor Rho and its co-factor NusG is suppression of ubiquitous antisense transcription genome-wide...
