Bridge- and solvent-mediated intramolecular electronic communications in ubiquinone-based biomolecular wires.

Scientific reports

Liu XY, Ma W, Zhou H, Cao XM, Long YT.
PMID: 25996306
Sci Rep. 2015 May 21;5:10352. doi: 10.1038/srep10352.

Intramolecular electronic communications of molecular wires play a crucial role for developing molecular devices. In the present work, we describe different degrees of intramolecular electronic communications in the redox processes of three ubiquinone-based biomolecular wires (Bis-CoQ0s) evaluated by electrochemistry...

PMID: 26983655
Acta Neuropsychiatr. 2003 Oct;15(5):266-73. doi: 10.1034/j.1601-5215.2003.00045.x.

BACKGROUND AND AIMS: The isoprenoid pathway was assessed in 15 patients with chronic fatigue syndrome (CFS). The pathway was also assessed in individuals with differing hemispheric dominance to assess whether hemispheric dominance has any correlation with these disease states.METHODS:...

Coenzyme Q10 Supplementation Modulates NFκB and Nrf2 Pathways in Exercise Training.

This study reports the effects of Q10, coenzyme Q10 or ubiquinone, a component of the electron transport chain in mitochondria, on nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB), inhibitors of kappa B (IκB), nuclear factor (erythroid-derived 2)-like 2...

Marinibactrum halimedae gen. nov., sp. nov., a gammaproteobacterium isolated from a marine macroalga.

International journal of systematic and evolutionary microbiology

Nishijima M, Adachi K, Sano H, Yamasato K.

Int J Syst Evol Microbiol. 2015 Nov;65(11):3866-3871. doi: 10.1099/ijsem.0.000502.

Phylogenetic and taxonomic characterization was performed for a bacterium, designated strain Q-192T, isolated from the surface of the green macroalga Halimeda sp., collected from the subtropical Ishigaki Island, Japan. The isolate was a polysaccharide-producing, Gram-stain-negative, aerobic, rod-shaped, motile bacterium...

Superoxide Dismutase Inhibition of Oxidation of Ubiquinol and Concomitant Formation of Hydrogen Peroxide.

Bioscience, biotechnology, and biochemistry

Nakayama T, Hashimoto M, Hashimoto K.
PMID: 27396880
Biosci Biotechnol Biochem. 1997 Jan;61(12):2034-8. doi: 10.1271/bbb.61.2034.

We measured ubiquinone (CoQ0) and hydrogen peroxide (H2O2) formed in the process of oxidation of ubiquinol (CoQ0H2). We found that copper-zinc superoxide dismutase and manganese superoxide dismutase inhibited both the CoQ0 formation and the H2O2 formation only in the...

Leber hereditary optic neuropathy: current perspectives.

Clinical ophthalmology (Auckland, N.Z.)

Clin Ophthalmol. 2015 Jun 26;9:1165-76. doi: 10.2147/OPTH.S62021. eCollection 2015.

Leber hereditary optic neuropathy (LHON) is one of the most common inherited optic neuropathies causing bilateral central vision loss. The disorder results from point mutations in mitochondrial DNA and subsequent mitochondrial dysfunction. The primary cell type that is lost...

Taxonomic heterogeneity of strains comprising Gluconacetobacter hansenii.

The Journal of general and applied microbiology

Navarro RR, Uchimura T, Komagata K.
PMID: 12501359
J Gen Appl Microbiol. 1999 Dec;45(6):295-300. doi: 10.2323/jgam.45.295.

The taxonomic standing of Gluconacetobacter hansenii was clarified through phenotypic characteristics, quinones, DNA base composition, DNA relatedness, and the production of gluconic and ketogluconic acids from glucose. All strains that Gosselé et al. (Syst. Appl. Microbiol., 4, 338-368, 1983)...

Systematic study of the genus Acetobacter with descriptions of Acetobacter indonesiensis sp. nov., Acetobacter tropicalis sp. nov., Acetobacter orleanensis (Henneberg 1906) comb. nov., Acetobacter lovaniensis (Frateur 1950) comb. nov., and Acetobacter estunensis (Carr 1958) comb. nov. .

Thirty-one Acetobacter strains obtained from culture collections and 45 Acetobacter strains isolated from Indonesian sources were investigated for their phenotypic characteristics, ubiquinone systems, DNA base compositions, and levels of DNA-DNA relatedness. Of 31 reference strains, six showed the presence...

Chemotaxonomic and phylogenetic analyses of Sphingomonas strains isolated from ears of plants in the family Gramineae and a proposal of Sphingomonas roseoflava sp. nov. .

Chemotaxonomic and phylogenetic characteristics of Sphingomonas strains isolated from plants of the family Gramineae were investigated. All strains contained the monosaccharide (glucuronic acid) type of glycosphingolipid (GSL-1). Most were found also to contain the oligosaccharide-type glycosphingolipids. Fatty acid and...

Ubiquinone-1 Induces External Deamino-NADH Oxidation in Potato Tuber Mitochondria.
