FIG. 5.

Candidate regulatory elements and genes involved in ILV degradation and FAD in gamma- and betaproteobacteria. Only conserved members of the predicted ILV/FA regulons are shown. Genes are arranged by metabolic pathway. Genomes are arranged by taxonomic lineages. When the gene is present in the genome, the background colors denote the presence of the specific recognition motif in its upstream region. If the gene is preceded by two different regulatory motifs, it is shown by a diagonally separated bicolor square. Genes without any candidate regulatory motifs described in this study are indicated by the gray background color. Empty crossings denote the absence of an orthologous gene in the genome.
