Identification of putative A. aeolicus ςN-dependent promoters. Close matches to the consensus ςN-binding motif were identified immediately upstream of dhsU, glnB, nirB, AQ_087, and AQ_1119 ORFs in the A. aeolicus genome sequence. Putative ςN-binding motifs are shown in boldface, as are the ATG start codons. Possible ribosome binding sites are underlined.
