Protein-Ubiquinone Interaction: Synthesis and Biological Properties of Ethoxy Ubiquinone Derivatives

Biochemistry, 1994
For investigation of the protein-ubiquinone interaction in the succinate-cytochrome c reductase region of the bovine heart mitochondrial electron-transport chain, ethoxy-substituted ubiquinone derivatives, 2-ethoxy-3-methoxy- or 3-ethoxy-2-methoxy-5-methyl-6-decyl-1,4-benzoquinone (EtOQ0C10) and 2,3-diethoxy-5-methyl-6-decyl-1,4-benzoquinone [(EtO ...

An ubiquinone-binding protein in mitochondrial NADH-ubiquinone reductase (complex I)

Biochemical and Biophysical Research Communications, 1986
An ubiquinone-binding protein (QP) was purified from mitochondrial NADH-ubiquinone reductase (Complex I). Complex I was separated into 3 fragments: a fraction of hydrophobic proteins, that of soluble iron-sulfur protein (IP) and soluble NADH dehydrogenase of flavoprotein by a procedure involving the resolution with DOC and cholate, followed by ethanol ...

Interaction of ubiquinone and vitamin K3 with mitochondrial succinate-ubiquinone oxidoreductase

Biochemical and Biophysical Research Communications, 1992
Two new methods have been devised for measuring fumarate reduction by beef heart succinate-ubiquinone oxidoreductase with quinols as electron donors. In one assay the quinone is maintained in the reduced state by coupling fumarate reduction with the DT-diaphorase reaction, in the other assay by the presence of excess dithionite. The advantages of these

The Chemistry of Ubiquinone

1967
Publisher Summary This chapter describes the chemical knowledge of the ubiquinones. It discusses new results from studies of the biosynthesis of ubiquinone, some new data concerning the mass spectrometry of the ubiquinones. Mass spectrometry has proved to be extremely useful in this research. A study of the mass spectra of a series of ubiquinones and

Ubiquinone: cholesterol's reclusive cousin

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2003
Coenzyme Q10 (CoQ10) is the predominant form of ubiquinone in man. CoQ10 functions as an electron carrier in the mitochondrial respiratory chain as well as serving as an important intracellular antioxidant. Lowered blood and tissue concentrations of CoQ10 have been reported in a number of diseases, although whether this deficiency is the cause or an ...
