Figure 10 From: Inter-genomic displacement via lateral gene transfer of bacterial trp operons in an overall context of vertical genealogy Phylogenetic tree of TrpEa sequences. TrpEa proteins from Pae and Psy fall into TCG-3 instead of into TCG-2. Paralogs Asp_1, Npu_1, Asp_2 and Npu_2 were generated by a gene duplication that preceded speciation of Asp and Npu. Asp_2 and Npu_2 were arbitrarily used for concatenate input (Fig. 2). TCG-7 is not very cohesive.Back to article page
