Down the Iron Path: Mitochondrial Iron Homeostasis and Beyond
Cellular iron homeostasis and mitochondrial iron homeostasis are interdependent. Mitochondria must import iron to form iron–sulfur clusters and heme, and to incorporate these cofactors along with iron ions into mitochondrial proteins that support ...

Clinical and genetic aspects of defects in the mitochondrial iron-sulfur cluster synthesis pathway [PDF]
Iron-sulfur clusters are evolutionarily conserved biological structures which play an important role as cofactor for multiple enzymes in eukaryotic cells.

Cluster and fold stability of E. coli ISC-type ferredoxin.
Iron-sulfur clusters are essential protein prosthetic groups that provide their redox potential to several different metabolic pathways. Formation of iron-sulfur clusters is assisted by a specialised machine that comprises, among other proteins, a ...

Crystallographic snapshots of sulfur insertion by lipoyl synthase [PDF]
Lipoyl synthase (LipA) catalyzes the insertion of two sulfur atoms at the unactivated C6 and C8 positions of a protein-bound octanoyl chain to produce the lipoyl cofactor. To activate its substrate for sulfur insertion, LipA uses a [4Fe-4S] cluster and S-

Insights from 125Te and 57Fe nuclear resonance vibrational spectroscopy: a [4Fe-4Te] cluster from two points of view. [PDF]
Iron-sulfur clusters are common building blocks for electron transport and active sites of metalloproteins. Their comprehensive investigation is crucial for understanding these enzymes, which play important roles in modern biomimetic catalysis and ...

Spectral decomposition of iron-sulfur clusters
The near universal availability of UV-Visible spectrophotometers makes this instrument a highly exploited tool for the inexpensive, rapid examination of iron-sulfur clusters. Yet, the analysis of iron-sulfur cluster reconstitution experiments by UV-Vis spectroscopy is notoriously difficult due to the presence of broad, ill-defined peaks. Other types of

Structural Basis of RICs Iron Donation for Iron-Sulfur Cluster Biogenesis
Escherichia coli YtfE is a di-iron protein of the widespread Repair of Iron Centers proteins (RIC) family that has the capacity to donate iron, which is a crucial component of the biogenesis of the ubiquitous family of iron-sulfur proteins.

Sensing iron availability via the fragile [4Fe-4S] cluster of the bacterial transcriptional repressor RirA [PDF]
Rhizobial iron regulator A (RirA) is a global regulator of iron homeostasis in many nitrogen-fixing Rhizobia and related species of α-proteobacteria.

Lights on Iron-Sulfur Clusters
The biogenesis of iron-sulfur proteins within a living cell is traditionally investigated by enzyme activity measurements and radiolabeling techniques. In this issue of Chemistry and Biology, Hoff et al. introduce a non-invasive fluorescence-based method to trace the formation of iron-sulfur clusters at high sensitivity.
