  • The functions of the highly reduced mitochondria (mitosomes) of microsporidians are not well-characterized. Here, the authors show that theTrachipleistophora hominismitosome is the site of iron–sulfur cluster assembly and that its retention is likely linked to its role in cytosolic and nuclear iron–sulfur protein maturation.

  • [2Fe-2S] protein cofactors are essential for life and are synthesized on ISCU2 scaffolds. Here, the authors show that hydrophobic interaction of two conserved N-terminal tyrosines induces ISCU2 dimerization and concomitant [2Fe-2S] cluster synthesis.

  • Mitochondrial ferredoxins FDX1 and FDX2 are assigned to specifically donate electrons to steroidogenesis, Fe–S protein biogenesis, heme a formation or lipoylation. The proteins’ functions can be swapped by mutually exchanging short peptide segments.
