Figure 3
Distribution of tRNAs in the Aquificales . Left: The total numbers of encoded tRNAs including the absence (+0) or presence (+1) of selenocysteine tRNA (tRNA-SeC) are given. Phylogenetic tree as in Figure 1; Right: anticodons specified by the following colors: red – tRNA with this anticodon encoded in all Aquificales; blue – tRNA encoded in the Aquificaceae only. Other colors represent the absence or presence of a tRNA with this anticodon, as defined in the phylogenetic tree on the left. For example, tRNA-SeC is present in all Aquificaceae except for Hydrogenobaculum sp., and is additionally found in the non-Aquificaceae species D. thermolithotrophum and T. ammonificans.
