Genome-wide identification of transcription start sites yields a novel thermosensing RNA and new cyclic AMP receptor protein-regulated genes in Escherichia coli

Abstract

Intergenic regions often contain regulatory elements that control the expression of flanking genes. Using a deep-sequencing approach, we identified numerous new transcription start sites in Escherichia coli, yielding a new thermosensing regulatory RNA and seven genes previously unknown to be under the control of the global regulator CRP.
