Figure 6From: A DNA element recognised by the molybdenum-responsive transcription factor ModE is conserved in Proteobacteria, green sulphur bacteria and ArchaeaFormula used to calculate I seq , the Kullback-Leibler distance [26], where i is the position within the site, p b is the frequency of that base in the genome, and f b,i is the observed frequency of each base at that position (from the weight matrix). Values for p b were calculated from the percentage G+C content of the genome sequence.Back to article page
