Test of the Halpern-Bruno proportionality. Observed rate of evolution versus the predictions based on the nucleotide frequencies in the binding motif in S. cerevisiae. Each point represents the predicted and observed rates at a given position in a motif. For each factor the proportionality has been normalized by the total number of substitutions observed in the corresponding binding sites. See text for details.
