News in Ubiquinone Biosynthesis
Ubiquinone (named because of its ubiquitous presence in organisms) functions as an electron carrier in the mitochondrial respiratory chain. Pierrel et al. (2010) have described the presence of new actors in the biosynthesis of this venerable molecule.

Ubiquinone and related compounds. XXXVIII. Biological oxidation of ubiquinone.
Ubiquinone-2 (1) was oxidized to 6-[7-carboxy-3-methyl- (2E, 6E)-2, 6-octadienyl]-2, 3-dimethoxy-5-methyl-1, 4-benzoquinone (2) and 6-[6, 7-dihydroxy-3, 7-dimethyl- (E)-2-octenyl]-2, 3-dimethoxy-5-methyl-1, 4-benzoquinone (3) by the 6000×g supernatant of guinea-pig liver homogenate in the presence of nicotinamide-adenine dinucleotide (NAD)- and ...

Cerebellar defects in Pdss2 conditional knockout mice during embryonic development and in adulthood
PDSS2 is a gene that encodes one of the two subunits of trans-prenyl diphosphate synthase that is essential for ubiquinone biosynthesis. It is known that mutations in PDSS2 can cause primary ubiquinone deficiency in humans and a similar disease in mice ...

Biosynthesis of ubiquinone and ubichromenol in vitamin A-deficient rats
1. The concentrations of ubiquinone and ubichromenol increased in the livers, but not in the intestines and kidneys, of rats maintained on a diet deficient in vitamin 2. After short time intervals (e.g.

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 ...

A Ubiquinone-binding Site Regulates the Mitochondrial Permeability Transition Pore.
We have investigated the regulation of the mitochondrial permeability transition pore (PTP) by ubiquinone analogues. We found that the Ca2+-dependent PTP opening was inhibited by ubiquinone 0 and decylubiquinone, whereas all other tested quinones ...

The regulation of the biosynthesis of ubiquinone in the rat
The urinary excretion of p-hydroxybenzoate was not altered by ubiquinone feeding, but, although decreased considerably, was not eliminated in protein deficiency.
