title: DNA-binding properties of the Bacillus subtilis and Aeribacillus pallidus AC6 σ(D) proteins.
abstract: σ(D) proteins from Aeribacillus pallidus AC6 and Bacillus subtilis bound specifically, albeit weakly, to promoter DNA even in the absence of core RNA polymerase. Binding required a conserved CG motif within the -10 element, and this motif is known to be recognized by σ region 2.4 and critical for promoter activity.
