Analysis of the target size dependence.

<p>The percentage of target proteins with a TM-score of the SQ, RW, and RR templates equal to or greater than 0.5 as a function of the target protein size is presented. The horizontal axis represents the sequence length of the target proteins. The vertical axis represents the percentage of the target proteins with the TM-scores of SQ, RW, and RR templates equal to or greater than 0.5 for a given target size. The lines are colored in black, blue, and red for the SQ, RW, and RR templates, respectively. The dotted lines correspond to the data in which the contributions of protein folds that exhibit topological similarity to the target proteins are excluded.
