Sequence logos of A/T-rich motifs upstream of the σ32 promoters. WCONSENSUS was used to search sequences upstream of the −35 element of 50 σ32 promoters (excluding repE). Distal, Proximal, and Complete motifs were identified from the search windows −46 to −60, −36 to −51, and −36 to −60, respectively, by aligning the promoters with respect to their −35 elements and assigning the first “T” of the −35 motif as position −35.
