malfunction | defects in human electron transfer flavoprotein or ETF-QO result in a metabolic disease known as multiple acyl-CoA dehydrogenation deficiency (MADD) or glutaric acidemia type 2. Death within the neonatal period occurs if the defects are severe | Homo sapiens |

additional information | electron transfer flavoprotein structure analysis and FAD binding, overview | Homo sapiens |
physiological function | in the mitochondrial matrix, the oxidation of fatty acids and several amino acids including lysine, leucine, valine, and isoleucine is coupled to the main mitochondrial respiratory chain through an electron transfer pathway involving electron transfer flavoprotein, electron transfer flavoprotein ubiqunone oxidoreductase, i.e. ETF-QO, and ubiquinone. Electron transfer flavoprotein contains a flavin adenine dinucleotide cofactor FAD that accepts electrons from 10 flavoprotein dehydrogenases, and transfers them to ETF-QO in the inner mitochondrial membrane. Electrons enter ETF-QO through its [4Fe-4S]-1+21 iron-sulfur cluster, are transferred to an FAD, and finally to ubiquinone | Paracoccus denitrificans |
