Genome wide binding sites of NsrR in uropathogenic E.coli CFT073
We applied ChIP-seq to identify genome wide binding targets of NsrR in E.coli CFT073. NsrR is a nitric oxide sensitive regulator of transcription.  Genome wide binding targets of NsrR have been identified in E.coli K12 using ChIP-chip. The genome of CFT073 is about 0.6Mb larger than that of K12. In this study,  we identify the novel NsrR binding sites in CFT073. Overall design: The nsrR gene was modified by the addition of DNA sequences encoding a C-terminal 3X-Flag tag, and the tagged gene was integrated into the chromosome. NsrR bound DNA was isolated by chromatin immunoprecipitation and  it was sequenced using Miseq platform.
