| Type: | Conserved_site | Name: | Electron transfer flavoprotein, beta-subunit, conserved site |
| Description: | The electron transfer flavoprotein (ETF) [, ] serves as a specific electronacceptor for various mitochondrial dehydrogenases. ETF transfers electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase. ETF is anheterodimer 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 arole in a redox process and feed electrons to ferredoxin. The beta subunit protein is distantly related to and forms aheterodimer with the alpha subunit . | Short Name: | ET-Flavoprotein_bsu_CS |
