This paper reveals how RfaH activates virulence gene expression by transforming its structure and stabilizing paused transcription complexes through interactions with ops hairpins.

This study uses single-molecule fluorescence microscopy to show that bacterial RNA polymerase-promoter open complex formation follows a branched pathway with varying stability.

The paper identifies a conserved Arg residue in multi-subunit RNA polymerases that uses a two-pronged strategy to select against 2’dNTPs by interacting with both the 2’OH and 3’OH groups.

The paper investigates how the closure of the RNA polymerase active site stabilizes the backtracked state during transcription, showing that trigger loop interactions with NTP substrates influence this process.
