Functional Diversity of Homologous Oxidoreductases—Tuning of Substrate Specificity by a FAD-Stacking Residue for Iron Acquisition and Flavodoxin Reduction

Antioxidants, 2023
Although bacterial thioredoxin reductase-like ferredoxin/flavodoxin NAD(P)+ oxidoreductases (FNRs) are similar in terms of primary sequences and structures, they participate in diverse biological processes by catalyzing a range of different redox ...

Mutations in DMI3 and SUNN Modify the Appressorium-Responsive Root Proteome in Arbuscular Mycorrhiza

Molecular Plant-Microbe Interactions, 2006
Modification of the Medicago truncatula root proteome during the early stage of arbuscular mycorrhizal symbiosis was investigated by comparing, using two-dimensional electrophoresis, the protein patterns obtained from non-inoculated roots and roots ...

Discovery and characterization of BlsE, a radical S-adenosyl-L-methionine decarboxylase involved in the blasticidin S biosynthetic pathway. [PDF]

PLoS ONE, 2013
BlsE, a predicted radical S-adenosyl-L-methionine (SAM) protein, was anaerobically purified and reconstituted in vitro to study its function in the blasticidin S biosynthetic pathway.

Properties of two clostridial flavodoxins [PDF]

Biochimica et Biophysica Acta (BBA) - Enzymology, 1971
Abstract 1. 1. Flavodoxins have been purified from Clostridium pasteurianum and Clostridium MP and their properties examined. Clostridium MP flavodoxin, like flavodoxins from C. pasteurianum and Peptostreptococcus elsdenii, has a molecular weight of about 14 000, it contains 1 molecule of FMN, and it replaces ferredoxin as an electron carrier in ...

Chloroplast Redox Status Modulates Genome-Wide Plant Responses during the Non-host Interaction of Tobacco with the Hemibiotrophic Bacterium Xanthomonas campestris pv. vesicatoria

Frontiers in Plant Science, 2017
Non-host resistance is the most ample and durable form of plant resistance against pathogen infection. It includes induction of defense-associated genes, massive metabolic reprogramming, and in many instances, a form of localized cell death (LCD) at the ...

Characterization of putative iron responsive genes as species-specific indicators of iron stress in Thalassiosiroid diatoms

Frontiers in Microbiology, 2011
Iron (Fe) availability restricts diatom growth and primary production in large areas of the oceans. The physiological and molecular response to Fe limitation differs among diatom species, making it difficult to assess the Fe nutritional health of ...

Diversity and Evolutionary History of Iron Metabolism Genes in Diatoms. [PDF]

PLoS ONE, 2015
Ferroproteins arose early in Earth's history, prior to the emergence of oxygenic photosynthesis and the subsequent reduction of bioavailable iron. Today, iron availability limits primary productivity in about 30% of the world's oceans.

Interaction of flavodoxin with cyanobacterial thylakoids

Photosynthesis Research, 1993
Flavodoxin from the cyanobacterium Anabaena PCC 7119 has been shown to mediate, under illumination, the transfer of electrons from the thylakoidal membranes that were isolated from the same organism, to both the enzyme ferredoxin-NADP(+) reductase and cytochrome c.
