The RCSB PDB also provides a variety of tools and resources. The late-onset form of GA II disorder is almost exclusively associated with mutations in the electron transfer flavoprotein dehydrogenase (ETFDH) gene. Some mutations in the ETFDH gene prevent the production of the electron transfer flavoprotein dehydrogenase enzyme. Electron transfer flavoprotein-ubiquinone oxidoreductase (ETF-QO) is a 4Fe4S flavoprotein located in the inner mitochondrial membrane.

It is Electron transferring flavoprotein. 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. This enzyme is normally active in the mitochondria, the energy-producing centers in cells. 5.^ Crystal structure of Paracoccus denitrificans electron transfer flavoprotein: structural and electrostatic analysis of a conserved flavin binding domain. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. An electron transfer flavoprotein (ETF) or electron transfer flavoprotein complex (CETF) is a flavoprotein located on the matrix face of the inner mitochondrial membrane and functions as a specific electron acceptor for primary dehydrogenases, transferring the electrons to terminal respiratory systems such as electron-transferring-flavoprotein dehydrogenase.

Electron-transferring flavoproteins (ETFs) have been found in all kingdoms of life, mostly assisting in shuttling electrons to the respiratory chain for ATP production. 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. The particles also catalyze the ATP-dependent reduction of NAD+ by enzymatically reduced ETF. Duine, unpublished results), the enzyme may indeed exist).
