Extended Data Fig. 5: Full phylogenetic tree of SUF/SMS (phylogram), corresponding to Fig. 4a.
From: An early origin of iron–sulfur cluster biosynthesis machineries before Earth oxygenation
Colours of branches correspond to the colour scheme used in Fig. 3 (Bacteria: Terrabacteria: marine blue, Gracilicutes: light blue, CPR: dark blue, Fusobacteria: grey blue; Archaea: Cluster I: orange and II: red). Bootstrap values > 80% are indicated by dots on branches. The scale bar indicates the average of number substitutions per site. The genomic context of genes coding for SUF and SMS components is indicated in front of the tree, centred around SufB and SmsB (brown and light brown, respectively). SufA: pink, SufC: yellow, SufD: dark green, SufS: light blue, SufE: turquoise SufT: dark blue, SufU: violet, SmsC: light green).
