In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group , which may be in the form of FAD or flavin mononucleotide (FMN).
The interface between the two monomers of a single dimer of an ACAD contains the FAD binding sites and has extensive bonding interactions. In contrast, the interface between the two dimers has fewer interactions. There are a total of 4 active sites within the tetramer, each of which contains a single FAD molecule and an acyl-CoA substrate ...
This led to the discovery that the protein studied required not riboflavin but flavin mononucleotide to be catalytically active. [ 6 ] [ 7 ] Similar experiments with D -amino acid oxidase [ 8 ] led to the identification of flavin adenine dinucleotide (FAD) as a second form of flavin utilised by enzymes.
The International Union of Pure and Applied Chemistry (IUPAC) defines "coenzyme" a little differently, namely as a low-molecular-weight, non-protein organic compound that is loosely attached, participating in enzymatic reactions as a dissociable carrier of chemical groups or electrons; a prosthetic group is defined as a tightly bound ...
FAD, or flavin adenine dinucleotide, is a prosthetic group (a non-polypeptide unit bound to a protein that is required for function) that consists of an adenine nucleotide and a flavin mononucleotide. [10] FAD is a unique electron acceptor.
The flavin moiety is often attached with an adenosine diphosphate to form flavin adenine dinucleotide (FAD), and, in other circumstances, is found as flavin mononucleotide (or FMN), a phosphorylated form of riboflavin. It is in one or the other of these forms that flavin is present as a prosthetic group in flavoproteins.
The E3 subunit, called the Dihydrolipoyl dehydrogenase enzyme, is characterized as a homodimer protein wherein two cysteine residues, engaged in disulfide bonding, and the FAD cofactor in the active site facilitate its main purpose as an oxidizing catalyst.
