Recycling of Bacterial RNA Polymerase by the Swi2/Snf2 ATPase RapA

K. Inlow, D. Tenenbaum, L. J. Friedman, J. Kondev, J. Gelles

This study uses single-molecule fluorescence microscopy to show RapA removes RNA polymerase from DNA after termination via ATP hydrolysis, enabling RNAP recycling in E. coli.

Alternative transcription cycle for bacterial RNA polymerase

T. T. Harden, K. S. Herlambang, M. Chamberlain, J.-B. Lalanne, C. D. Wells, G.-W. Li, R. Landick, A. Hochschild, J. Kondev, J. Gelles

The paper observes bacterial RNA polymerase (RNAP) remaining bound to DNA after termination and restarting transcription in reverse, producing antisense transcripts, using single-molecule fluorescence microscopy and genome-wide RNA sequencing.
