Maximum likelihood phylogenetic tree of LeuRS across the three domains of life. Numbers on the nodes indicate bootstrap support. Only the support values for major clades are shown for clarity. Members of the Halobacteriales are highlighted in red. The tree was rooted using amino acid sequences of isoleucyl-tRNA synthetase from Thermotoga maritima, Aquifex aeolicus, Aeropyrum pernix and Methanopyrus kandleri. Details of this tree are shown in Additional file 1: Figure S1.
