Structures and functions of mitochondrial ABC transporters [PDF]
A small number of physiologically important ATP-binding cassette (ABC) transporters are found in mitochondria. Most are half transporters of the B group forming homodimers and their topology suggests they function as exporters.

Role of GSH and Iron-Sulfur Glutaredoxins in Iron Metabolism—Review
Glutathione (GSH) was initially identified and characterized for its redox properties and later for its contributions to detoxification reactions. Over the past decade, however, the essential contributions of glutathione to cellular iron metabolism have ...

Mammalian frataxin directly enhances sulfur transfer of NFS1 persulfide to both ISCU and free thiols [PDF]
Friedreich's ataxia is a severe neurodegenerative disease caused by the decreased expression of frataxin, a mitochondrial protein that stimulates iron sulfur (Fe-S) cluster biogenesis.

Identification of Sequences Encoding Symbiodinium minutum Mitochondrial Proteins. [PDF]
The dinoflagellates are an extremely diverse group of algae closely related to the Apicomplexa and the ciliates. Much work has previously been undertaken to determine the presence of various biochemical pathways within dinoflagellate mitochondria ...

NFS1 undergoes positive selection in lung tumours and protects cells from ferroptosis [PDF]
Environmental nutrient levels impact cancer cell metabolism, resulting in context-dependent gene essentiality. Here, using loss-of-function screening based on RNA interference, we show that environmental oxygen levels are a major driver of differential ...

Clinical, biochemical, and genetic spectrum of seven patients with NFU1 deficiency [PDF]
Disorders of the mitochondrial energy metabolism are clinically and genetically heterogeneous. An increasingly recognized subgroup is caused by defective mitochondrial iron-sulfur (Fe-S) cluster biosynthesis, with defects in 13 genes being linked to ...

Interaction of the Streptomyces Wbl protein WhiD with the principal sigma factor σHrdB depends on the WhiD [4Fe-4S] cluster [PDF]
The bacterial protein WhiD belongs to the Wbl family of iron–sulfur [Fe-S] proteins present only in the actinomycetes. In Streptomyces coelicolor, it is required for the late stages of sporulation, but precisely how it functions is unknown.

Methanosarcina acetivorans contains a functional ISC system for iron-sulfur cluster biogenesis
Background The production of methane by methanogens is dependent on numerous iron-sulfur (Fe-S) cluster proteins; yet, the machinery involved in Fe-S cluster biogenesis in methanogens remains largely unknown.
