A. Organisms with Elf1 and histone orthologues identified in this study. The number in the black circle indicates the number of Elf1 and histone orthologues found. An empty circle indicates that no orthologue was detected. Histone searches were not done in for eukaryotic organisms. B. Alignment of Elf1 orthologues identified in this study. Organisms are indicated on the left. Numbers of trimmed residues are indicated in brackets at their respective position. Residues that are identical or similar to the consensus are shown with a blue or cyan background, respectively.
