The Fe Protein: An Unsung Hero of Nitrogenase [PDF]
Although the nitrogen-fixing enzyme nitrogenase critically requires both a reductase component (Fe protein) and a catalytic component, considerably more work has focused on the latter species.

Fe-S Protein Synthesis in Green Algae Mitochondria [PDF]
Iron and sulfur are two essential elements for all organisms. These elements form the Fe-S clusters that are present as cofactors in numerous proteins and protein complexes related to key processes in cells, such as respiration and photosynthesis, and ...

Functional expression of the nitrogenase Fe protein in transgenic rice. [PDF]
AbstractEngineering cereals to express functional nitrogenase is a long-term goal of plant biotechnology and would permit partial or total replacement of synthetic N fertilizers by metabolization of atmospheric N2. Developing this technology is hindered by the genetic and biochemical complexity of nitrogenase biosynthesis.

Spectroscopic analysis of protein Fe–NO complexes [PDF]
The toxic free radical NO (nitric oxide) has diverse biological roles in eukaryotes and bacteria, being involved in signalling, vasodilation, blood clotting and immunity, and as an intermediate in microbial denitrification. The predominant biological mechanism of detecting NO is through the formation of iron nitrosyl complexes, although this is a ...

Dre2, a Conserved Eukaryotic Fe/S Cluster Protein, Functions in Cytosolic Fe/S Protein Biogenesis [PDF]
In a forward genetic screen for interaction with mitochondrial iron carrier proteins in Saccharomyces cerevisiae, a hypomorphic mutation of the essential DRE2 gene was found to confer lethality when combined with Delta mrs3 and Delta mrs4. The dre2 mutant or Dre2-depleted cells were deficient in cytosolic Fe/S cluster protein activities while ...

Canopy position has a profound effect on soybean seed composition [PDF]
Although soybean seeds appear homogeneous, their composition (protein, oil and mineral concentrations) can vary significantly with the canopy position where they were produced.

Functional Characterization of the Eukaryotic Cysteine Desulfurase Nfs1p from Saccharomyces cerevisiae [PDF]
Previous studies have indicated that the essential protein Nfs1 performs a crucial role in cellular iron-sulfur (Fe/S) protein maturation. The protein is located predominantly in mitochondria, yet low amounts are present in cytosol and nucleus.
