In this study transcriptional start sites (TSS) for H. pylori 26695 were determined Overall design: To detect the complement of transcripts expressed from H. pylori, we collected three independent biological replicates (B1 – B3) from 26695 wild type strain grown to mid-exponential (OD 600 ~0.6) phase under microaerophilic conditions at 37°C in BHI medium. For all three samples, total RNA was extracted and subjected to differential RNA-seq (dRNA-seq) library preparation for primary transcriptome analysis as described previously (Sharma et al., 2010). Specifically, prior to cDNA library construction half of each RNA sample was treated with 5’ terminator exonuclease (+TEX samples), which degrades RNAs containing a 5’-monophosphate (5’-P) and, thus, enriches for primary transcripts containing 5’-triphosphates (5’-PPP). The other half of each sample was left untreated (-TEX samples) and thus contains both primary transcripts (5’-PPP) and processed RNAs (5’-P). Less...
