Crystal structure of Aquifex aeolicus σ(N) bound to promoter DNA and the structure of σ(N)-holoenzyme

The bacterial σ factors confer promoter specificity to the RNA polymerase (RNAP). One alternative σ factor, σ(N), is unique in its structure and functional mechanism, forming transcriptionally inactive promoter complexes that require activation by specialized AAA(+) ATPases. We report a 3.4-Å resolu...
