Real-time capture of σN transcription initiation intermediates reveals mechanism of ATPase-driven activation by limited unfolding
Abstract Bacterial σ factors bind RNA polymerase (E) to form holoenzyme (Eσ), conferring promoter specificity to E and playing a key role in transcription bubble formation. σN is unique among σ factors in its structure and functional mechanism, requiring activation by specialized AAA+ ATPases. EσN f...
