The paper shows mitochondrial ferritin uses a unique iron-O2 chemistry mechanism involving a conserved Tyr residue and mixed-valent ferroxidase centre, differing from cytosolic ferritin.

The paper demonstrates that Arabidopsis BRUTUS and BRUTUS-LIKE2 proteins bind iron and exhibit redox properties, supporting their role as plant iron sensors.

This study characterizes the iron-sulfur cluster binding properties of Nar1 using spectroscopic and mass spectrometry methods, revealing multiple cluster binding sites and oxygen sensitivity.
