Figure 4From: Significance of two distinct types of tryptophan synthase beta chain in Bacteria, Archaea and higher plantsUnrooted phylogenetic tree (radial view) of the TrpEa protein family. Organismal acronyms are defined in Table 1. Phylogenetic reconstruction of the inferred amino-acid sequence was accomplished by the neighbor-joining method using the PHYLIP program. The detailed order of branching for cyanobacterial and higher-plant sequences is shown in Figure 3. Archaeal proteins are visualized in magenta, and the yellow line indicates the TrpEa protein from C. trachomatis, which is probably encoded by a pseudogene.Back to article page
