FIG. 1.

Nucleotide sequence of the DNA fragment studied in this report. Nucleotide numbering is taken from GenBank sequence M57613. The shaded bases are those protected from the action of hydroxyl radicals by binding of BkdR. Part of the coding sequences for bkdR and bkdA1 are translated to show the location of these genes. The arrows indicate the 5′ ends of the DNA fragments summarized in Table 2. The bend center is marked by the inverted triangle, and the transcriptional start is marked +1. There is no identifiable −35 hexamer.
