Electron transfer flavoprotein:ubiqionone oxidoreductase (ETF-QO) is a component of the mitochondrial respiratory chain that together with electron transfer flavoprotein (ETF) forms a short pathway that transfers electrons from 11 different mitochondrial flavoprotein dehydrogenases to the ubiquinone pool. Zahlreiche mitochondriale Enzyme beinhalten Flavinadenindinukleotid als kovalent gebundenes Coenzym. Alternatively spliced transcript variants have been … [1] [2] It is part of the electron transport chain. Information on EC 1.5.5.1 - electron-transferring-flavoprotein dehydrogenase for references in articles please use BRENDA:EC1.5.5.1. 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. Flavoprotein glucose dehydrogenase was originally found in some fungi already several years ago [34] but the finding has meanwhile not been confirmed in the literature (however, since we found dye-linked glucose dehydrogenase activity in several fungi (B.W. FAD-2 is recovered by adding FAD to the isolated ETF. Heterodimeric electron transfer flavoprotein that accepts electrons from several mitochondrial dehydrogenases, including acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase (PubMed:27499296, PubMed:15159392, PubMed:15975918, PubMed:9334218, PubMed:10356313). This is a preview … In humans, it is encoded by the ETFDH gene. Electron-transferring flavoprotein (ETF) from the anaerobic bacterium Megasphaera elsdenii is a heterodimer containing two FAD cofactors. Es nimmt zwei Elektronen auf, und reduziert dabei ein eigenes kovalent gebundenes FAD zu FADH2. 2014; 289:5145–5157. Das Elektronentransferierende Flavoprotein (abgekürzt ETF) ist ein Komplex aus zwei Proteinketten, der in Bakterien und Eukaryoten Teil der Atmungskette ist. ETF-QO is very highly conserved in evolution and the recombinant enzyme from the bacterium Rhodobacter sphaeroides has allowed the mutational analysis of a number of residues that the structure suggested are involved in modulating the reduction potential of the cofactors. ►Structural and mutagenesis studies suggest that FAD is the electron donor to ubiquinone (UQ). Electron transfer flavoprotein-ubiquinone oxidoreductase (ETF-QO) is a 4Fe4S flavoprotein located in the inner mitochondrial membrane. Biochemistry 38, 1977-89, (1999). The enzyme is found in both prokaryotes and eukaryotes and contains a flavin and FE-S cluster. The electron-transferring flavoprotein activity, purified 22-fold, was separated into two major flavoprotein components, A and B, after polyacrylamide gel electrophoresis. Required for … Copyright © 2010 Elsevier B.V. All rights reserved. Information on EC 1.5.5.1 - electron-transferring-flavoprotein dehydrogenase. [1] [2] It is part of the electron transport chain. Electron Transfer Flavoproteins. This structure reveals ETF-QO to be a monotopic membrane protein with the cofactors, FAD and a [4Fe–4S]+ 1+2 cluster, organised to suggests that it is the flavin that serves as the immediate reductant of ubiquinone. Das Elektronentransferierende Flavoprotein (abgekürzt ETF) ist ein Komplex aus zwei Proteinketten, der in Bakterien und Eukaryoten Teil der Atmungskette ist. Synonyms. Proceedings of the National Academy of Sciences, https://de.wikipedia.org/w/index.php?title=Elektronentransferierendes_Flavoprotein&oldid=193301941, „Creative Commons Attribution/Share Alike“. It catalyzes ubiquinone (UQ) reduction by ETF, linking oxidation of fatty acids and some amino acids to the mitochondrial respiratory chain. Während NADH löslich ist und zu den Komplexen der Atmungskette frei diffundieren kann, ist FADH2 fest an das jeweilige Enzym gebunden. & Beinert, H. (1956) J. Biol. 5.^ Crystal structure of Paracoccus denitrificans electron transfer flavoprotein: structural and electrostatic analysis of a conserved flavin binding domain. Glutaric acidemia type II. The interaction between the physiological electron transfer partners trimethylamine dehydrogenase (TMADH) and electron-transferring flavoprotein (ETF) from Methylophilus methylotrophus has been examined with particular regard to the proposal that the former protein “imprints” a conformational change on the latter.
