FIG. 6.
Putative cis-regulatory motifs. Multiple alignments are represented as sequence logos. x axis, nucleotide position within motif; y axis, bit score. Arrows indicate putative half-sites. (A) BvgA-binding motif from regions upstream of Bvg-activated genes. Dashed line, variable-length (0- to 2-nt) spacer between half-sites. (B) Fim box. Solid lines, box 1 and box 2; dashed line, beginning of poly(C) tract. (C and D) FNR box (C) and palindromic motif (D) from regions upstream of Bvgi-b genes.
