WebFlavins are commonly utilized in a variety of both 1- and 2-electron transfers and reactions involving oxygen activation. In addition, flavins have also been shown to function as acid/base catalysts or nucleophilic catalysts, to electrostatically stabilize transition states, and to serve simply as structural components in some enzymes. ... Flavins (from Latin flavus, "yellow") are organic compounds, like their base, pteridine. They are formed by the tricyclic heterocycle isoalloxazine. The biochemical source is the vitamin riboflavin. The flavin moiety is often attached with an adenosine diphosphate to form flavin adenine dinucleotide (FAD), and, in … See more Both free and protein-bound flavins are photoreducible, that is, able to be reduced by light, in a mechanism mediated by several organic compounds, such as some amino acids, carboxylic acids and amines. This property of … See more Flavin adenine dinucleotide is a group bound to many enzymes including ferredoxin-NADP+ reductase, monoamine oxidase, D-amino acid oxidase, glucose oxidase, xanthine oxidase, and acyl CoA dehydrogenase.
