Decision tree rules used for predicting MTase substrate specificity.

Decision tree rules were based on the maximum isoelectric point (Max pI), similarity of expression profiles (Cluster; the numbering of clusters that group MTases with similar gene expression profiles is given in Figure 3), fold assignment (Fold) and cellular localization (Localization). Columns R, P and F show the Recall, Precision and F-measure values calculated for each substrate specificity class with non-zero R. The number of MTases with the substrate specificity predicted by each of the rules is shown in column N.
