FIG. 1.

The gltCA intergenic region. Likely transcription start sites of the gltC and gltA genes, their −10 and −35 regions, and the gltA initiation codon are in boldface. Directions of transcription and translation are indicated by horizontal arrows. The mutations in the region are shown above the sequence with their allele numbers. The apparent GltC-binding Box I and Box II sequences (2) are underlined and double underlined, respectively. A TnrA binding sequence is underlined with dashes. Above this site the nucleotides that appear to interact with TnrA in the DNase I protection assay are shown by a horizontal line, and the TnrA consensus sequence (15) is presented. The fusions in pLG200, pLG203, and pLG219 contain fragments with coordinates from −160 to +119. The vertical arrows indicate upstream or downstream junctions for the truncated fusions in plasmids pLG700 (positions −56 to +119), pLG702 (positions −45 to +119), pLG708 (positions −160 to +24), and pLG711 (positions −160 to +3). The numbering of the sequence is with respect to the gltA transcription start point (2).
