FIG. 6.
Sequence logo for sequenced σB promoters resulting from alignments of the sequenced σB promoters presented in Table 3 with known L. monocytogenes σB promoters (upstream from lmo0596, prfA, fri, gbuA, lmo1421, lmo0699, lmo1433, lmo2230, opuCA, inlA, lmo2434, bsh, and rsbV) (4, 9, 24, 30, 32). The logo is composed of stacks of letters for the positions in the sequence. The overall height of each stack indicates the sequence conservation at that position (measured in bits), while the height of each letter reflects the relative frequency of the corresponding nucleic acid at that position.
