Electron transferring flavoprotein

Definition

Electron transfer flavoproteins are dimeric proteins that function as mobile electron carriers. These proteins are grouped in three classes: (a) flavoproteins serving as electron acceptors for flavoprotein dehydrogenases in mammalian mitochondria and in several bacteria; (b) those heterodimeric proteins that function in nitrogen fixation and are structurally related to mammalian electron transfer flavoprotein; (c) putative proteins related to mammalian electron transfer flavoprotein, encoded by genes in the fix region of the Escherichia coli genome.

Electron Transfer Flavoproteins: Structure and the Reductive Half-Reaction

Electron transfer flavoprotein (ETF) and its electron acceptor, ETF-ubiquinone oxidoreductase (ETF-QO) play essential roles in the β-oxidation of fatty acids, branched-chain amino acids, lysine, tryptophan, and N-methyl amino acids (N-methyl-glycine and N,N-dimethylglycine) in mammalian mitochondria. Mechanistic...
