Localization of SNPs in the promoter regions of the investigated derivative A. actinomycetemcomitans (Aa) strains with the S colony phenotype. The consensus promoter region was previously defined by Wang et al. (41). Please note that with the exception of 4R/4S, the sequences of all other presently investigated R/S pairs and the ATCC type strain of A. actinomycetemcomitans deviate from the published promoter region with respect to 3 nucleotides downstream of the −10 region.
