Maximum likelihood trees of GDH-3 and GDH-4 (A) The phylogenetic tree is based on 457 unambiguously aligned amino acid positions of GDH-3. The Γ shape parameter, α, and the fraction of invariable sites, P_inv, were estimated to 1.07 and 0.06, respectively. (B) The phylogenetic tree is based on 1141 unambiguously aligned amino acid positions of GDH-4. The Γ shape parameter, α, and the fraction of invariable sites, P_inv, were estimated to 1.14 and 0.14, respectively. The trees are arbitrarily rooted. Labeling as in Figure 1.
