The numbers represents ORF according to www. pseudomonas.com. [45].
Fold changes observed after growth in LB and BSM + succinate, respectively. Positive values indicate that transcripts were more abundant in the mutant than in the wild type. Negative values indicate that transcripts were less abundant in the mutant than in the wild type.
The locations of the CA-motif are given according to the start codon (A of the ATG = +1).
