FIG. 2.

Diagram and nucleotide sequence of the ytmI-ytlI promoter region. At the top is a diagram of the ytmI-ytlI locus from the SubtiList website (http://genolist.pasteur.fr/SubtiList/). The numbers at either end refer to the nucleotide positions in the chromosome. At the bottom is the nucleotide sequence of the ytmI-ytlI promoter region. Uppercase letters denote the noncoding, intergenic region between ytmI and ytlI. Lowercase letters specify the coding sequences of ytmI and ytlI. The ATG and TTG start codons are labeled with gene names and arrows for ytmI and ytlI. Solid arrows mark the transcriptional start sites for both genes as identified by primer extension analysis (Fig. 1). The −10 regions of both promoters are labeled, and the sequences are enclosed in rectangles.
