    Abstract: PURPOSE: A method for producing TNF Related Apoptosis Inducing Ligand(TRAIL) protein, and for crystallizing the TRAIL protein and the three-dimensional structure thereof are provided, thereby TRAIL protein having improved activity, which specifically kills cancer cells and cells infected by virus, can be produced. CONSTITUTION: The TRAIL having sequence No. 2 is produced by the steps of: inserting the human TRAIL protein gene into a plasmid to produce pET3a-TLS; transforming E. coli with pET3a-TLS to produce E. coli BL21-TLS(pET3a-TLS)(KCCM-10169); incubating the transformed E. coli BL21-TLS(pET3a-TLS)(KCCM-10169) at 22 to 37 deg. C and adding IPTG during incubation to express the TRAIL gene; breaking the cells, collecting insoluble fragments, denaturing and refolding the fragments to collect soluble protein; treating the soluble fragment and soluble protein with cationic exchange chromatography and size excluding chromatography to isolate and purify the TRAIL protein. The TRAIL protein is crystallized by using a solution containing 20 to 40% of PEG MME550, 0.02 to 0.5M of bicine, and 0.02 to 0.5M of sodium chloride, then reacting 24 μg of TRAIL protein and a precipitation solution containing 20 to 30% of PEG MME550, 10 to 100mM bicine, and 5 to 20mM of cadmium chloride. The three-dimensional structure of TRAIL protein consists of an inner sheet comprising strand A, A'', H, C and H; an outer sheet comprising strand B', B, G, D and E; and a loop which links ten strands.
