sigma(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 sigma region 2.4 and critical for promoter activity.
