  1. 1 C. diphtheriae genes described previously as part of the DtxR regulon [14, 15]
  2. 2 Two DtxR binding sites were identified in front of the coding region.
  3. 3 A single DtxR binding site is involved most likely in regulation of adjacent coding regions located on the opposite DNA strand [14, 15].
