Extended Data Fig. 2: Taxonomic distribution of all components of the five different systems on the phylogeny (cladogram) of Bacteria.
From: An early origin of iron–sulfur cluster biosynthesis machineries before Earth oxygenation
Bootstrap values > 80% are indicated by dots on branches. The size of dots corresponds to the ratio of presence of each system in each clade/phylum. The colour of dots corresponds to the biochemical role of each component as in Fig. 1.
