Phylogram of the evolutionary relationship of the pART family. Evolutionary relationships of the amino acid sequences in the catalytic core of the pARTs shown in Figure 6 are illustrated as a maximum a posteriori phylogram (MAP) of Bayesian Markov Chain Monte Carlo analysis (pP = 0.92). Posterior probabilities were converted into percentages and are shown above the branches. Members of the five pART family subgroups are color-coded as in Figure 2: subgroup 1 = red, 2 = pink, 3 = orange, 4 = green, 5 = grey. Hs = Homo sapiens, Mm = Mus musculus.
