Frataxin interacts functionally with mitochondrial electron transport chain proteins.
Frataxin deficiency is the main cause of Friedreich ataxia, an autosomal recessive neurodegenerative disorder. Frataxin function in mitochondria has not been fully explained yet. In this work, we show that Saccharomyces cerevisiae frataxin orthologue Yfh1p interacts physically with succinate dehydrogenase complex subunits Sdh1p and Sdh2p of the yeast mitochondrial electron transport chain and a...
متن کاملThe electron transport chain of serotonin-dense granules of platelets.
An electron transport chain has been found and partially characterized in highly purified membranes of serotonin granules isolated from porcine platelets. In these membranes NADH, but not NADPH, is oxidized when ferricyanide or catalytic amounts of cytochrome c were present. The reduced minus oxidized spectrum of these serotonin granule membranes shows a characteristic cytochrome b spectrum wit...
متن کاملThe Photosynthetic Electron Transport Chain of Chlamydomonas reinhardi
Previous studies (l-3) have described the application of mutant strains of Chlamydomonas reinhardi to an investigation of the enzymatic pathway of triphosphopyridine nucleotide reduction during photosynthesis. Two of these mutants, m-116 and ac-1.41, appear to be genetically blocked in the light-dependent Oz-evolving step of photosynthesis. The validity of this conclusion rests on the following...
متن کاملModeling the electron transport chain of purple non-sulfur bacteria
Purple non-sulfur bacteria (Rhodospirillaceae) have been extensively employed for studying principles of photosynthetic and respiratory electron transport phosphorylation and for investigating the regulation of gene expression in response to redox signals. Here, we use mathematical modeling to evaluate the steady-state behavior of the electron transport chain (ETC) in these bacteria under diffe...
متن کاملResistance to co-occurring phages enables marine synechococcus communities to coexist with cyanophages abundant in seawater.
Recent reports documenting very high viral abundances in seawater have led to increased interest in the role of viruses in aquatic environments and a resurgence of the hypothesis that viruses are significant agents of bacterial mortality. Synechococcus spp., small unicellular cyanobacteria that are important primary producers at the base of the marine food web, were used to assess this hypothes...
