Expression analysis of Escherichia coli MG1655 K-12 WT and M-bM-^HM-^Ffnr mutant

Project description:Investigation of whole genome gene expression level changes in a Escherichia coli MG1655 K-12 ?fnr mutant, compared to the wild-type strain. The mutations engineered into this strain produce a strain lacking the FNR protein. WT strains were grown under aerobic and anaerobic growth conditions. A six chip study using total RNA recovered from two separate cultures of Escherichia coli MG1655 K-12 WT (aerobic and anaerobic) and two separate cultures of the ?fnr mutant strain (anaerobic). Each chip measures the expression level of 4,661 genes from Escherichia coli MG1655 K-12 with eight 60-mer probes per gene, with each probe represented twice on the array.

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.
