Localization of NsrR binding sites in the Escherichia coli genome

Project description:NsrR is a nitric oxide sensitive regulator of transcription. In Escherichia coli, NsrR is a repressor of the hmp gene encoding the flavohemoglobin that detoxifies nitric oxide. Several other transcription units (including ytfE, ygbA and hcp-hcr) are known to be subject to regulation by NsrR. In this study, chromatin immunoprecipitation and microarray analysis was used to identify NsrR binding sites in the chromosome of Escherichia coli strain MG1655. Keywords: ChIP-chip

RNA-seq data of Escheirchia coli K12 MG1655 of overexpression of GcvB, MicA, ArcZ, RyhB or CyaR sRNAs

Project description:To study the regulatory outcome of Hfq-mediated sRNA-target interactions, we measured the change in gene expression following overexpression of each of five well-established sRNAs: GcvB, MicA, ArcZ, RyhB and CyaR. For each of the studied sRNAs we applied RNA-seq to two E. coli K-12 MG1655 strains: (1) a WT strain or a strain deleted of the sRNA gene; (2) a strain overexpressing the sRNA, either artificially from a plasmid or from the endogenous sRNA gene by changing the growth condition. For GcvB induction, the E. coli K-12 MG1655 Z1 gcvB::Cm, pZA12-gcvB and the E. coli K-12 MG1655 Z1 gcvB::Cm, pTP-011 strains were used. For MicA overexpression the E. coli K-12 MG1655lacIq pBRplac, pEF21-Hfq and the E. coli K-12 MG1655lacIq pMicA, pEF21-Hfq strains were used. For ArcZ induction the E. coli K-12 MG1655 Z1 arcZ::Cm, pZE12-ArcZ and the E. coli K-12 MG1655 Z1 arcZ::Cm, pJV300 strains were used. For RyhB overexpression the E. coli K-12 MG1655 ryhB::Cm and the E. coli K-12 MG1655 were used. For CyaR induction the E. coli K-12 MG1655 Z1 cyaR::Cm, pZE12-CyaR and the E. coli K-12 MG1655 Z1 cyaR::Cm, pJV300 strains were used. All E. coli strains used in this study were grown overnight in Luria Bertani (LB) medium at 37 °C with shaking (200 r.p.m.), diluted 100-fold in fresh LB medium, and re-grown with shaking at 37 °C to exponential phase, for GcvB (OD600 = 0.3) and for RyhB (OD600 = 0.5), or to stationary phase, for ArcZ WT, ArcZ M1, ArcZ M2 and CyaR (OD600 = 1.0) and for MicA (grown for 6 hr). For induction of ArcZ and GcvB, IPTG was added (1mM, 20 min). MicA was constitutively expressed and further induced at the end of growth with IPTG (1mM, 20 min). For induction of RyhB, the iron chelator 2,2'-Dipyridyl was added (200 μM, 30 min).

Hi-C study of the E. coli MG1655 chromosome

Project description:We performed Hi-C analysis of Escherichia coli MG1655 cells in exponential and stationary growth phase. We could detect long-range interactions predominantly in the Ori domain of the chromosome. Interestingly, the use of a new type of control revealed that these interactions are mostly crosslinking independent.

Psoralen binding across the Escherichia coli chromosome

Project description:We used trimethylpsoralen intercalation to map supercoiling across the E. coli chromosome. We treated E. coli cells with trimethylpsoralen and exposed them to UV light. Psoralen enters cells, intercalates between DNA base pairs, and crosslinks the two strands of DNA at a rate proportional to the local superhelical density. We then fragmented DNA and hybridized crosslinked and non-crosslinked DNA fragments separately to tiling microarrays. In total 14 samples; 6 for wild-type in stationary phase (3 replicates x 2 samples as there are crosslinked and non-crosslinked samples for each replicate); 4 for wild-type in mid-exponential phase (2 replicates x 2 samples); 4 for the delta hupAB mutant in stationary phase (2 replicates x 2 samples)
