Extended Data Fig. 9: Phylogenetic trees of MIS/NIF.
From: An early origin of iron–sulfur cluster biosynthesis machineries before Earth oxygenation
Left panel: phylogeny of MisS/NifS. The genomic context of genes of MIS/NIF is indicated in front of the tree, using MisS/NifS as markers (MisS: light red, MisU: blue, NifS: dark green, NifU: dark blue). Right panel: phylogeny of a concatenation of NifU/NifS and the closest group of MisU/MisS. The genomic context of genes of MIS/NIF is indicated in front of the tree, using MisS/NifS as markers (MisS: dark brown, MisU: light brown, NifS: light blue, NifU: dark blue, IscAnif: violet, other Nif genes (ClpX, CysE1, NifB, NifD, NIfE, NifF, NifH, NifK, NifM, NifN, NifQ, NifV, NifW, NifX, NifZ): grey). Bootstrap values > 80% are indicated by dots on branches. The scale bar indicates the average of number of substitutions per site. Colour of leaves corresponds to phyla or classes for Proteobacteria.
