Uneven Braking Spins RNA Polymerase into a Pause

Mol Cell. 2018 Mar 1;69(5):723-725. doi: 10.1016/j.molcel.2018.02.013.

Abstract

In this issue of Molecular Cell, Guo et al. (2018) and Kang et al. (2018) report structures of paused transcription complexes in which asynchronous translocation inhibits nucleotide addition, allowing for global rearrangements in RNA polymerase stabilized by RNA hairpin and NusA.
