Recombinant S. Japonicum Glutathione S-transferase/GST protein

GST, also known as, Glutathione S-transferase, represents a major group of detoxification enzymes. GST acts by catalyzing the reaction of glutathione with an acceptor molecule to form an S-substituted glutathione (S=sulfur) . The reactions utilizing glutathione contribute the transformation of a wide range of compounds, including carcinogens, therapeutic drugs, and products of oxidative stress. As well as its enzymatic activities, GST may also bind toxins and function as transport protein. Because of this, an early term for GSTs was ligandin. GST was originally separated from Schistosomajaponicum but currently isolated from recombinant E. coli source. Recombinant Schistosoma japonicum GST was expressed in E. coli and purified by conventional chromatography techniques.
