Estimates of both positive and purifying selection at each amino acid site of SpA calculated from the ratio of non-synonymous (Ka) to synonymous substitutions (Ks) [62]. Graphical display of selecton results with FirstGlance in Jmol where the Ka/Ks scores are colored-coded. Significant positive and purifying sites (P-value < 0.05) are colored in orange (color number 1) and magenta (color number 4), respectively
