Ferredoxins from Nitrogen-Fixing Bacteria
Two ferredoxins have been purified from N2-fixing Mycobacterium flavum. Ferredoxin I had a minimum molecular weight (by amino acid analysis) of 11 230 and contained 7.4 mol Fe and 7.0 mol S2per mol. The ratio of the absorbance at 400 nm to that at 275 nm was 0.7. Ferredoxin I1 had a minimum molecular weight of 13478 and contained 3.4 mol Fe and 3.2 mol S2per mol. The ratio of the absorbance at ...
متن کاملA post genomic characterization of Arabidopsis ferredoxins.
In higher plant plastids, ferredoxin (Fd) is the unique soluble electron carrier protein located in the stroma. Consequently, a wide variety of essential metabolic and signaling processes depend upon reduction by Fd. The currently available plant genomes of Arabidopsis and rice (Oryza sativa) contain several genes encoding putative Fds, although little is known about the proteins themselves. To...
متن کاملStructure, function and evolution of bacterial ferredoxins.
During the past few years, the field of ironsulfur proteins has not ceased expanding. This evolution is due to the development of sophisticated methods such as electron paramagnetic resonance, M~Sssbauer or X-ray crystallography and to a fruitful interdisciplinary collaboration between biochemists, chemists and physicists. These advances have brought to light how widespread the non-heme iron pr...
متن کاملWhat Determines the Redox Potential of Ferredoxins
For many cytochromes P450 (P450), the electrons are transferred from the reductase to the P450 via a [2Fe-2S] cluster ferredoxin (e.g. putidaredoxin, terpredoxin or adrenodoxin). A similar role is played by several plant-type ferredoxins to transfer electrons from photosystem I to NADP. Other ferredoxins like E. coli ferredoxin are probably involved in the biogenesis of iron-sulfur clusters. To...
متن کاملStructure-function studies of [2Fe-2S] ferredoxins.
The ability to overexpress [2Fe-2S] ferredoxins in Escherichia coli has opened up exciting research opportunities. High-resolution x-ray structures have been determined for the wild-type ferredoxins produced by the vegatative and heterocyst forms of Anabaena strain 7120 (in their oxidized states), and these have been compared to structural information derived from multidimensional, multinuclear...
