FIG. 2.

B. pertussis nucleotide sequence encompassing the 5′ region of bhuR. An 871-bp region of the chromosome of strain UT25 was sequenced on both strands. The BhuR putative start codon is underlined, and the N-terminal 149-amino-acid region of BhuR is shown. The line above nucleotides 338 through 356 indicates the position of a potential Fur-binding site. Bracketed nucleotides represent the proposed ECF ς factor −10 and −35 promoter elements. Lowercase letters indicate nucleotides of the 871-bp region that overlap B. pertussis nucleotide sequence contigs found in the Sanger Centre database.
