The SdhE protein is found on the mitochondrial membrane is it is important for creating energy via a process named the electron transport chain.
Is SDH found in the cytosol?
Selak et al. (2005) showed that SDH dysfunction in cells raised the levels of succinate and, that succinate serves as an intracellular messenger between the mitochondria and the cytosol.
What class of enzyme is succinate dehydrogenase?
Succinate dehydrogenase belongs to the class of oxidoreductase enzymes. One substrate is oxidised and another gets reduced in the reaction. It catalyses the oxidation of succinate to fumarate in the Krebs cycle with simultaneous reduction of FAD+ to FADH2.
