Position of the predicted NarL binding site in the upstream region of torC. The NarL BS TACCCT is located on the forward strand with respect to the target operon torCAD starting at position -209 bp (red color). All positions are relative to the first nucleotide of the start codon of torC. (a) The fragment of the upstream region of the torCAD operon containing the NarL BS predicted by the PWM model trained on the adjusted data set. (b) Histogram of all positions of NarL BSs in the database. The red line indicates the position of the predicted BS.
