Effects of coenzyme Q10 supplementation on the serum levels of amylase, adenosine deaminase, catalase, and total antioxidant capacity in women with type 2 diabetes mellitus: A randomized, double-blind placebo-controlled trial

open access: yesJournal of Research in Medical Sciences, 2018
Background: Increased levels of reactive oxygen species is a key factor involved in the pathogenesis of type 2 diabetes mellitus (T2DM). Coenzyme Q10(CoQ10) is a nonenzymatic antioxidant that restores other antioxidants.

Mitochondrial respiration without ubiquinone biosynthesis.

open access: yesHuman Molecular Genetics, 2013
Ubiquinone (UQ), a.k.a. coenzyme Q, is a redox-active lipid that participates in several cellular processes, in particular mitochondrial electron transport. Primary UQ deficiency is a rare but severely debilitating condition. Mclk1 (a.k.a.

Nourishing and health benefits of coenzyme Q10

open access: yesCzech Journal of Food Sciences, 2008
Coenzyme Q10 is an important mitochondrial redox component and endogenously produced lipid-soluble antioxidant of the human organism. It plays a crucial role in the generation of cellular energy, enhances the immune system, and acts as a free radical ...

Kinase Activity of ArcB from Escherichia coli Is Subject to Regulation by Both Ubiquinone and Demethylmenaquinone

open access: yesPLoS ONE, 2013
Expression of the catabolic network in Escherichia coli is predominantly regulated, via oxygen availability, by the two-component system ArcBA. It has been shown that the kinase activity of ArcB is controlled by the redox state of two critical pairs of ...

Liposoluble quinone promotes the reduction of hydrophobic mineral and extracellular electron transfer of Shewanella oneidensis MR-1

open access: yesThe Innovation, 2021
Summary: A large number of reaction systems are composed of hydrophobic interfaces and microorganisms in natural environment. However, it is not clear how microorganisms adjust their breathing patterns and respond to hydrophobic interfaces.

The ubiquinone system in Oomycetes

open access: yesMycoscience, 1995
Ubiquinone (Coenzyme Q) systems of 32 strains belonging to Oomycetes (Saprolegniales and Lagenidiales) were investigated. The fungi were isolated from various animals with fungal infections and both freshwater and marine environments. The major component in the fungi was Coenzyme Q-9 without exception.

Gene network reconstruction identifies the authentic trans-prenyl diphosphate synthase that makes the solanesyl moiety of ubiquinone-9 in Arabidopsis.

open access: yesThe Plant Journal, 2012
Ubiquinone (coenzyme Q) is the generic name of a class of lipid-soluble electron carriers formed of a redox active benzoquinone ring attached to a prenyl side chain.

The isoprenyl chain length of coenzyme Q mediates the nutritional resistance of fungi to amoeba predation

open access: yesmBio
Amoebae are environmental predators feeding on bacteria, fungi, and other eukaryotic microbes. Predatory interactions alter microbial communities and impose selective pressure toward phagocytic resistance or escape which may, in turn, foster virulence ...

Alternative oxidase (AOX) constitutes a small family of proteins in Citrus clementina and Citrus sinensis L. Osb. [Poster-B186] [PDF]

open access: yes, 2018
The alternative oxidase (AOX) protein is present in plants, fungi and some invertebrates. It is involved in the mitochondrial respiratory chain, providing an alternative route for the transport of electrons, leading to the reduction of oxygen to form ...
