Evolutionary relationships among GSII enzymes from prokaryotes and eukaryotes. The phylogenetic analyses were based on 333 amino acid characters from 196 taxa. The 50% majority-rule consensus tree from the Bayesian analyses [48, 49] is shown as inferred from 20,002 trees as described in the Methods. Nodes with BBP support > 0.95 are represented by thick lines. RAxML [50, 51] bootstrap values are indicated for nodes recovered in both analyses. RAxML values are not indicated for terminal bifurcations. Eubacterial GSII_B were used as the outgroup and considered monophyletic. The area of the triangles representing collapsed clades is not proportional to the number of taxa within the clade.
