Functioni

Promotes the biosynthesis of heme as well as the assembly and repair of iron-sulfur clusters by delivering Fe2+ to proteins involved in these pathways (PubMed:17092311). May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe2+ to Fe3+ (PubMed:17092311). May be able to store large amounts of the metal in the form of a ferrihydrite mineral by oligomerization (PubMed:17092311). Binds to the mitochondrial cysteine desulfurase NIFS1 and increases its activity (PubMed:22511606).2 Publications

Catalytic activityi

4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
