Conserved Site

Electron transfer flavoprotein, beta-subunit, conserved site (IPR000049)

Short name: ET-Flavoprotein_bsu_CS


The electron transfer flavoprotein (ETF) [PMID: 2326318, PMID: 8525056] serves as a specific electron acceptor for various mitochondrial dehydrogenases. ETF transfers electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase. ETF is an heterodimer that consist of an alpha and a beta subunit and which bind one molecule of FAD per dimer. A similar system also exists in some bacteria. The beta subunit of ETF is a protein of about 28 Kd which is structurally related to the bacterial nitrogen fixation protein fixA which could play a role in a redox process and feed electrons to ferredoxin. The beta subunit protein is distantly related to and forms a heterodimer with the alpha subunit IPR001308.
