(Submitter supplied) Oxidative stress that originates from reactive oxygen species (ROS) is an inevitable consequence of aerobic respiration in bacteria. Three transcription factors (TFs), OxyR, SoxR, and SoxS play a critical role in transcriptional regulation of the defense system. However, the full genome-wide regulatory potential of them remains elusive. Here, we comprehensively reconstruct genome-wide OxyR, SoxR, and SoxS transcriptional regulatory networks in Escherichia coli under oxidative stress. more...

(Submitter supplied) A transcription factor (TF), OmpR, plays a critical role in transcriptional regulation of the defense system for osmotic stress in bacteria. However, its full genome-wide regulatory potential is unknown. Here, we perform a genome-scale reconstruction of the OmpR regulon in Escherichia coli K-12 MG1655. Integrative data analysis reveals that a total of 37 genes in 24 transcription units (TUs) belong to OmpR regulon. more...

(Submitter supplied) The response to acid stress is a fundamental process in bacteria. Three transcription factors, GadE, GadW, and GadX (GadEWX) are known to play a critical role in the transcriptional regulation of glutamate-dependent acid resistance (GDAR) system in Escherichia coli K-12 MG1655. However, the regulatory role of GadEWX in coordinating interacting cellular functions is still unknown. Here, we comprehensively reconstruct genome-wide GadEWX transcriptional regulatory network in E. more...

(Submitter supplied) In bacteria the defence system to counter oxidative stress is orchestrated by three transcriptional factors – SoxS, SoxR and OxyR. Although the transcriptional regulon of these factors are known in many bacteria, similar data is not available for K. pneumoniae. To address this data gap, oxidative stress was induced in K. pneumoniae MGH 78578 using paraquat and the corresponding regulon was identified using RNA-seq. more...

(Submitter supplied) We integrated transcription factor binding regions and mRNA transcript abundance to elucidate the PurR regulon experimentally. To measure transcription factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 harboring PurR-8myc under various conditions.

(Submitter supplied) Escherichia coli strain MG1655 was grown in a Zn-depleted custom-built chemostat. Culture volume (120 ml), temperature (37 oC) and stirring speed (440 rpm) were maintained. Steady state values for pH and OD600 were 6.9 and 0.6, respectively. Chemostats were grown for 50 h to allow five culture volumes to pass through the vessel and allow an apparent (pseudo-)steady state to be reached. At this point, ZnSO4.7H2O in water was added to a final concentration of 0.2 M in the chemostat. more...
