Regulated enzyme
WebMetallothionein (MT), a primary antioxidant enzyme involved in the metabolism and detoxification of heavy metal, has been recognized as a molecular target for chemoprevention by natural anti-cancer agents, but the cellular signaling mechanisms that associate MT gene regulation are not yet clearly understood. WebEnzyme Regulation Since activation energy is such an important part to chemical reactions, and since enzymes play an integral part in lowering activation energies, it would make sense that cells have evolved complex mechanisms to regulate enzyme activity. Enzymes can be regulated in ways that increase or decrease their activity. One
