GST reduces lipid hydroperoxides through its Se-independent glutathione peroxidase activity. The enzyme also detoxifies lipid peroxidation end products such as 4-hydroxynonenal (4-HNE).The soluble GST is a 26 kDa protein which occurs as a dimer in all aerobic organisms. Each monomer has two domains, one that binds GSH and is an \/-structure similar to thioredoxin and the other, all helical, that binds the hydrophobic substrate. The GST -fusion protein expression system is a widely used recombinant protein expression system that allows a peptide or a regulatory protein domain to be expressed as a fusion to the C-terminus of Schistosoma japonicum GST. Fusion proteins also possess GST -enzymatic activity and can undergo dimerization similar to in vivo. The fusion protein can be purified via GST -affinity column chromatography. In most cases, the desired peptides or domains are removed from GST by applying a specific protease that recognizes and cleaves the linker between the protein domain and GST. The technique has been widely used to generate different kinds of proteins for crystallization, molecular immunology studies, the production of vaccines and studies involving protein-protein and protein-DNA interactions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bhp-desc\"\u003e\n\u003ch3 style=\"color:#1a5c58;margin:12px 0 4px\"\u003eBiological Activity\u003c\/h3\u003e\n\u003cp\u003eThe Specific activity is \u0026gt; 30 units\/mg, and is defined as the amount of enzyme that conjugate 1.0 umole of 1-chloro-2,4-dinitrobenzene (CDNB) with reduced glutathione per minute at pH 6.5 at 25C.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bhp-desc\"\u003e\n\u003ch3 style=\"color:#1a5c58;margin:12px 0 4px\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:0.92em\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eGreater than 90.0% as determined by SDS-PAGE.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eGST protein solution (1mg\/ml) containing PBS and 10% glycerol.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eStore at 4°C if entire vial will be used within 2-4 weeks.
