Figure 2From: Evolution of glutamate dehydrogenase genes: evidence for lateral gene transfer within and between prokaryotes and eukaryotesMaximum likelihood tree of GDH-2 The phylogenetic tree is based on 305 unambiguously aligned amino acid positions. The Γ shape parameter, α, and the fraction of invariable sites, Pinv, were estimated to 1.10 and 0.08, respectively. The tree is arbitrarily rooted. Labeling as in Figure 1 with the addition that Archaea are labeled in blue.Back to article page
