WebThe flavoproteins are some of the most-studied families of enzymes. Flavoproteins have either FMN or FAD ( flavin adenine dinucleotide) as a prosthetic group or as a cofactor. The flavin is generally tightly bound (as in adrenodoxin reductase, wherein the FAD is buried deeply). [1] About 5-10% of flavoproteins have a covalently linked FAD.
