Electron-transferring-flavoprotein dehydrogenase ("ETF dehydrogenase" or "electron transfer flavoprotein-ubiquinone oxidoreductase", EC 1.5.5.1) is an enzyme that transfers electrons from electron-transferring flavoprotein in the mitochondrial matrix, to the ubiquinone pool in the inner mitochondrial membrane. [cite journal |author=Ramsay RR, Steenkamp DJ, Husain M |title=Reactions of electron-transfer flavoprotein and electron-transfer flavoprotein: ubiquinone oxidoreductase |journal=Biochem. J. |volume=241 |issue=3 |pages=88392 |year=1987 |pmid=3593226 |doi=] It is part of the electron transport chain. The enzyme is found in both prokaryotes and eukaryotes and contains a flavin and FE-S cluster. [cite journal |author=Zhang J, Frerman FE, Kim JJ |title=Structure of electron transfer flavoprotein-ubiquinone oxidoreductase and electron transfer to the mitochondrial ubiquinone pool |journal=Proc. Natl. Acad. Sci. U.S.A. |volume=103 |issue=44 |pages=162127 |year=2006 |pmid=17050691 |doi=10.1073/pnas.0604567103] Deficiency in EFT dehydrogenase causes the human genetic disease multiple acyl-CoA dehydrogenase deficiency.
