A ubiquinol is an electron-rich (reduced) form of coenzyme Q (ubiquinone). The term most often refers to ubiquinol-10, with a 10-unit tail most commonly...

Rieske protein), 2 core proteins and 6 low-molecular weight proteins. Ubiquinol—cytochrome-c reductase catalyzes the chemical reaction QH2 + 2 ferricytochrome...

reduction of the lipophilic electron carrier Coenzyme Q (CoQ) between the ubiquinol and ubiquinone forms, can result in the net movement of protons across...

Ubiquinol oxidases (EC 1.10.3.11) are enzymes in the bacterial electron transport chain that oxidise ubiquinol into ubiquinone and reduce oxygen to water...

branched-chain amino acids oxidation (through flavin-linked dehydrogenases) to ubiquinol–cytochrome-c reductase (complex III) of the ETC: CoQ10 participates in...

Ubiquinol oxidase (H+-transporting) (EC 7.1.1.3, cytochrome bb3 oxidase, cytochrome bo oxidase, cytochrome bd-I oxidase) is an enzyme with systematic...

When Q accepts two electrons and two protons, it becomes reduced to the ubiquinol form (QH2); when QH2 releases two electrons and two protons, it becomes...

motive force (and accordingly, a ubiquinol-concentrated pool), the enzyme runs in the reverse direction. Ubiquinol is oxidized to ubiquinone, and the...

Ubiquinol-cytochrome c reductase complex assembly factor 2 is a protein that in humans is encoded by the UQCC2 gene. Located in the mitochondrial nucleoid...

stopping the flow of electrons to oxygen. Later studies revealed that Ubiquinol oxidase activity ceases first, and the still-active cytochromes reduce...
