ChIP-seq of the multiple antibiotic resistance activator (MarA) protein and RNA polymerase sigma70 subunit of Enterotoxigenic Escherichia coli strain H10407

ABSTRACT: The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmid pRGM9818. The strain was grown at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using antibodies against MarA, MarR or the RNA polymerase sigma 70 subunit. Libraries were prepared using DNA remaining after immunoprecipitation. Note that the MarR immunoprecipitations were not successful but the data served as a useful control for non-specifically immunoprecipitated DNA sequences.

ChIP-seq of the multiple antibiotic resistance repressor (MarR) protein of Enterotoxigenic Escherichia coli strain H10407

Project description:The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmids pAMNF (encoding an N-terminal MarR-3xFLAG fusion) or pAMNM (encoding an N-terminal MarR-8xmyc fusion). The cells was cultured at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using an anti-FLAG antibody (i.e. the strain encoding the MarR-8xmyc fusion was used as a control). Libraries were prepared using DNA remaining after immunoprecipitation.

Cyanophage MarR-type transcription factor regulates host RNase E expression

Project description:The marine picocyanobacterium Prochlorococcus contributes significantly to global primary production, and its abundance and diversity is shaped in part by viral infection. Here, we identified a cyanophage-encoded MarR-type transcription factor that induces gene expression of host Prochlorococcus MED4 endoribonuclease (RNase) E during phage infection. The increase in rne transcript levels relies on the phage (p)MarR-mediated activation of an alternative promoter that gives rise to a truncated, yet, enzymatically fully functional RNase E isoform. In this study, we demonstrate that pMarR binds to an atypical activator site downstream of the transcriptional start site and that binding is enhanced in the presence of Ca2+ ions. Furthermore, we show that dimeric pMaR interacts with the α subunit of RNA polymerase, and we identified amino acid residues S66, R67 and G106, which are important for Ca2+ binding, DNA binding and dimerization of pMarR, respectively.
