Locations of constitutive promoters of RNAP RpoD holoenzyme within prophages. Genomic SELEX screening was performed to search for promoters recognized by RNAP RpoD holoenzyme. Most of the prophages lack promoters with high-level activity. Significant peaks were detected in several prophages as indicated by asterisks: *a, argF promoter (CP4-6 prophage); *b, lit promoter (e14 prophage); *c, trkG promoter (Rac prophage); *d, smpB promoter (CP4-57 prophage boundary). See Fig. S2A for the binding sites of RNAP RpoD holoenzyme along the entire genome of E. coli K-12.
