Dissection of C. thermocellum σI-dependent promoters. The conservation of nucleotides shown in the alignment is divided into σI1-, σI2-, σI3-, σI4-, and σI6-dependent promoters. The promoter sequences of each σI regulon were taken from Fig. 1A. The most conserved nucleotides of each σI regulon are highlighted.
