Legend Figure1 shows the Z-curves for the original sequence. Figure2 shows the Z-curves for the rotated sequence beginning and ending in dif site or the maximum of the GC disparity curve. Short vertical red line indicates the indicator gene (such as dnaA, dnaN, gidA, hemE etc) location, and short up vertical dark blue arrow indicates the identified oriC location, short down vertical brown arrow indicates dif site location. Purple peaks with the diamonds indicates the DnaA box clusters.
