Project description:Mapping the occupancy of FNR, HNS, and IHF throughout the genome of Escherchia coli MG1655 K-12 using an affinity purified antibody under anerobic growth conditions. We also mapped the binding of the M-CM-^_ subunit of RNA Polymerase under both aerobic and anaerobic growth conditions. As a control, we also performed ChIP-chip on FNR in a M-bM-^HM-^Ffnr mutant strain of Escherchia coli MG1655 K-12. We also examined FNR immunoprecipitation at various FNR concentrations using IPTG and Ptac::fnr (PK8263). The M-bM-^HM-^Fhns/M-bM-^HM-^FstpA strains were also used. Descirbed in the manuscript Genome-scale Analysis of E. coli FNR Reveals the Complexity of Bacterial Regulon Structure Mapping of occupancy of FNR, NNS, IHF and M-CM-^_ of RNAP in the genome of Escherchia coli MG1655 K-12 under aerobic or anaerobic growth conditions. Immunoprecipitated DNA compared to INPUT for each sample.

Chip-chip from Escherichia coli MG1655 K-12, WT and ∆fnr strains

Project description:Mapping the occupancy of FNR, HNS, and IHF throughout the genome of Escherchia coli MG1655 K-12 using an affinity purified antibody under anerobic growth conditions. We also mapped the binding of the ß subunit of RNA Polymerase under both aerobic and anaerobic growth conditions. As a control, we also performed ChIP-chip on FNR in a ∆fnr mutant strain of Escherchia coli MG1655 K-12. We also examined FNR immunoprecipitation at various FNR concentrations using IPTG and Ptac::fnr (PK8263). The ∆hns/∆stpA strains were also used.

ChIP-chip of MG1655 with antibody against E. coli RNAP beta subunit under various conditions

Project description:We integrated RNAP binding regions (RBRs) and mRNA transcript abundance to determine segments of contiguous transcription originating from promoter regions. To measure RBRs at a genome scale, we employed a ChIP-chip method to E. coli K-12 MG1655 grown in the presence or absence of rifampicin under multiple growth conditions using antibody against E. coli RNAP beta subunit. A twelve ChIP-chip study using immunoprecipitated DNA (IP-DNA) from four separate culture conditions with and/or without rifampicin treatment. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes spaced 25 bp apart (25-bp overlap between two probes) across the E. coli genome (NimbleGen). Experiments were conducted as biological duplicates or triplicates (different cultures).

ArcA Chip-chip from Escherichia coli MG1655 K-12, WT and ∆arcA strains

Project description:Mapping the occupancy of ArcA throughout the genome of Escherchia coli MG1655 K-12 using an affinity purified antibody under anaerobic and aerobic growth conditions. As a control, we also performed ChIP-chip onArcA in a ∆arcA mutant strain of Escherchia coli MG1655 K-12. Described in the manuscript The response regulator ArcA uses a diverse binding site architechture to globally regulate carbon oxidation in E. coli
