ChIP-seq of Helicobacter pylori N6 wild-type and HP1021 deletion mutant under microaerophilic and aerobic conditions (optimal growth and oxidative stress conditions, respectively).


ABSTRACT: We performed DNA-protein interaction (ChIP-seq) analyses for Helicobacter pylori N6 wild-type (WT) and HP1021 deletion mutant (ΔHP1021::aphA-3) under oxidative stress (21% O2) and optimal microaerobic growth (5% O2) conditions. We detected 100 binding sites of HP1021 on the H. pylori N6 chromosome, most of which are promoter-located, likely affecting gene transcription. 84 of 100 identified HP1021 binding sites were located near promoter regions. EMSA and ChIP-qPCR confirmed the binding of HP1021 to the promoter region of a few genes.
