Figure 1From: APTE: identification of indirect read-out A-DNA promoter elements in genomesA combined promoter sequence consists of an A-form promoter element followed by a direct read-out promoter motif. The APE row indicates the signs of the APE values for the sequence in the Base row; with X denoting undetermined APE values [11]. The main parameters are the number of negative APE values in the APS (apelen), and the gap between the APS and the motif.Back to article page
