From: Detection of prokaryotic promoters from the genomic distribution of hexanucleotide pairs
The application of a simple sequence-dependent filter and the subsequent diminution of the threshold allows the detection of an otherwise missed promoter. Graphs reporting scores calculated for all hexanucleotide pairs located in the enlarged IR upstream of the B. subtilis ftsA gene. (A) No filter applied. (B) Sequence-dependent filtering (3 mismatches and 2 mismatches allowed respectively in the -35 and -10 boxes relative to the B. subtilis principal σ factor consensus sequence) followed by the reduction of the region-specific threshold from 3 to 2 standard deviations above of the mean.
