Prosthetic enzyme
WebbCofactor (biochemistry) The succinate dehydrogenase complex showing several cofactors, including flavin, iron–sulfur centers, and heme. A cofactor is a non- protein chemical compound or metallic ion that is required for an enzyme 's role as a catalyst (a catalyst is a substance that increases the rate of a chemical reaction ). Cofactors can be divided into two major groups: organic cofactors, such as flavin or heme; and inorganic cofactors, such as the metal ions Mg , Cu , Mn and iron–sulfur clusters. Organic cofactors are sometimes further divided into coenzymes and prosthetic groups. The term coenzyme refers specifically to enzymes and, as such, to the functional properties of a protein. On the other hand, "prosthetic group" emphasizes the nature of the binding of a cofactor to a protei…
