Fig 4. Sequence analysis of experimentally confirmed SigH promoters.
25 promoters experimentally identified in this research plus 7 previously identified promoters recognized by SigH were analyzed using the MEME analysis suite. A. LOGO showing consensus -10 and -35 promoter elements derived from these sequences. B. 25 promoter sequences that match the SigH consensus sequences. The position of the TSP and the ratio of heat stress-induced expression in wild type relative to expression in a ΔsigH strain are also shown. C. 7 promoter sequences that do not match the SigH consensus.
