Human DHODH is a ubiquitous FMN flavoprotein. Flavin mononucleotide binding domain interacts with a coenzyme of flavoprotein oxidoreductase enzymes, FMN. His thesis project revolved around the enzyme fumarase, which is not a flavoprotein. It has 2 cofactors&colon; FAD, and Flavoprotein. It uses electron transfer flavoprotein as its electron acceptor. It has 2 cofactors&colon; flavin, and flavoprotein. Flavin adenine dinucleotide in its oxidized form, FAD is a cofactor of flavoprotein oxidoreductase enzymes. The canonical squalene monooxygenase is a flavoprotein monooxygenase. This enzyme is flavoprotein (FAD). Electron transfer components are composed of flavoprotein (NADH&colon;ferredoxin oxidoreductase) and Rieske-type [FeS] ferredoxin. Cyclohexanone monooxygenase is a flavoprotein (FAD). DLD is a flavoprotein enzyme that oxidizes dihydrolipoamide to lipoamide. The photoreceptor protein in "Euglena" is likely a flavoprotein. Therefore, SDHA is a flavoprotein (Fp) due to the prosthetic group flavin adenine dinucleotide (FAD). This protein is a flavoprotein associated with the outer surface of the inner mitochondrial membrane.
