  1. a MSTs were identified by searching the B. cenocepacia J2315 genome with the position specific scoring matrix (PSSM) from the second generation motif. Only genes with a motif match within a potential promoter and within 300 bp of the predicted start codon are reported.
  2. b The location center of the predicted motif is reported as chromosome:nucleotide. (+) or (-) refers to the DNA strand encoding the motif sequence. The motif names in bold were used to generate the PSSM file.
  3. c Number of base pairs between the centre of the motif and the predicted translational start site.
  4. d Open reading frame number from the unpublished annotation of the B. cenocepacia J2315 genome. (+) and (-) refer to the DNA strand.
  5. e Gene and domain homologies were obtained using the standard protein-protein BlastP program as described in the methods. Genes in parantheses are downstream of the first orf following the motif and may be in the same operon.
  6. f Confirmed to be CepR regulated by either lux or lacZ transcriptional fusions.
