Identification of HP0244 regulon at different pH conditions

Transcriptional profiling of Helicobacter pylori comparing 26695 wild-type strain and a HP0244-deficient mutant 26695/∆HP0244::km treated at three different pH conditions (pH 7.4, pH 4.5 without urea, or pH 2.5 with 30 mM urea) for 30 min to define the HP0244 acid-responsive regulon Keywords: Genetic modification and stress response Wild type vs HP0244-deficient mutant at three different pH conditions (pH7.4, pH4.5 without urea, and pH2.5 with 30 mM urea). Three biological replicates for each pH condition: 3 wild type and 3 mutant, independently grown, pH treated, and harvested.
