Information on EC 1.5.5.1 - electron-transferring-flavoprotein dehydrogenase for references in articles please use BRENDA:EC1.5.5.1. AU - Costas, Amaya M.Garcia. 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. electron transferring flavoprotein complex was observed, providing the first direct observation of these mammalian complexes. Electron-transferring flavoproteins (ETFs) have been found in all kingdoms of life, mostly assisting in shuttling electrons to the respiratory chain for ATP production. ►Structural and mutagenesis studies suggest that FAD is the electron donor to ubiquinone (UQ). Hitherto, electron transfer (ET) between redox proteins has been deemed to occur via donor–acceptor binding, and diffusible reactive species are considered as deleterious side-products in such systems. Here we show that the electron-transferring flavoprotein (Etf) enzyme family exhibits far greater diversity than previously recognized, and we provide a phylogenetic analysis that clearly delineates bifurcating versus nonbifurcating members of this family. In the complex, electron density for the FAD domain of ETF is absent, indicating high mobility. We use cookies to help provide and enhance our service and tailor content and ads. 86551-03-3.
