Alignment of the −10 and −35 recognition sequences of the 17 σ^E target promoters characterised by S1 mapping, additionally including the previously characterised hrdD and cwg promoters (Buttner et al., 1990; Hong et al., 2002). The target genes are divided into Class I (one promoter, completely dependent upon σ^E), Class II (one promoter, partially dependent upon σ^E) and Class III targets (multiple promoters, one at least partially dependent upon σ^E). The corresponding σ^E consensus sequence, generated using WebLogo (Crooks et al., 2004), is shown above the alignment.
