In photosynthetic eukaryotes assembly components of iron-sulfur (Fe-S) cofactors have been studied in plastids and mitochondria, but how cytosolic and nuclear Fe-S cluster proteins are assembled is not known. We have characterized a plant P loop NTPase with sequence similarity to Nbp35 of yeast and

Iron-sulfur (Fe/S) protein maturation in the eukaryotic cytosol and nucleus requires conserved components of the essential CIA machinery. The CIA protein Nar1 performs a specific function in transferring an Fe/S cluster that is assembled de novo on the Cfd1-Nbp35 scaffold to apoproteins. Here, we

The essential P-loop NTPases Cfd1 and Nbp35 of the cytosolic iron-sulfur (Fe-S) protein assembly machinery perform a scaffold function for Fe-S cluster synthesis. Both proteins contain a nucleotide binding motif of unknown function and a C-terminal motif with four conserved cysteine residues. The

Maturation of iron-sulfur (Fe-S) proteins in eukaryotes requires complex machineries in mitochondria and cytosol. Initially, Fe-S clusters are assembled on dedicated scaffold proteins and then are trafficked to target apoproteins. Within the cytosolic Fe-S protein assembly (CIA) machinery, the

Biogenesis of iron-sulfur ([Fe-S]) proteins in eukaryotes requires the function of complex proteinaceous machineries in both mitochondria and cytosol. In contrast to the mitochondrial pathway, little is known about [Fe-S] protein assembly in the cytosol. So far, four highly conserved proteins (Cfd1,

Surveillance for bovine genetic diseases in Denmark identified a hitherto unreported congenital syndrome occurring among progeny of a Holstein sire used for artificial breeding. A genetic aetiology due to a dominant inheritance with incomplete penetrance or a mosaic germline mutation was suspected

Defects in the yeast cysteine desulfurase Nfs1 cause a severe impairment in the 2-thio modification of uridine of mitochondrial tRNAs (mt-tRNAs) and cytosolic tRNAs (cy-tRNAs). Nfs1 can also provide the sulfur atoms of the iron-sulfur (Fe/S) clusters generated by the mitochondrial and cytosolic Fe/S

The cytosolic iron-sulfur (Fe-S) protein assembly (CIA) machinery comprises 11 essential components and matures Fe-S proteins involved in translation and genome maintenance. Maturation is initiated by the electron transfer chain NADPH-diflavin reductase Tah18-Fe-S protein Dre2 that facilitates the
