Pervasive Transcription-coupled DNA repair in E. coli

Abstract

Transcription-Coupled DNA repair has been classically defined as the preferential repair of the template strand (TS) over the non-template strand (NTS). Here the authors challenge this classic model of TCR by using a genome-wide repair assay, CPD-seq, as well as RNA-seq, to show that TCR occurs across the entire E. coli genome – including NTS and intergenic regions.
