^aNucleotides that match the consensus CebR box sequence are underlined.

^bNucleotide position of the center of the CebR box relative to the transcriptional start site (TC) or the translational start site (TL).

^cAverage value from three quantitative-RT-PCR experiments. wt, wild type.

^dFrom the transcriptional start site of cebRp₁ (Fig. 5E).

^eNot detected because the cebR coding region was deleted in the ΔcebR mutant.

^fSGR6927 and SGR6928 are divergent. Two CebR boxes exist in the intergenic region between SGR6927 and SGR6928.
