X-RAY DIFFRACTION	THE STRUCTURE WAS SOLVED BY MULTIPLE ANOMALOUS DISPERSION (MAD) USING 5 DIFFERENT WAVELENGTH (2X FE-EDGE + 2X CU-EDGE + 1 REMOTE). THE DATA STATISTICS GIVEN CORRESPOND TO THE REFERENCE WAVELENGTH WHICH WAS USED FOR REFINEMENT. THE STRUCTURE WAS SOLVED WITH SHARP.	THROUGHOUT	2.4	20	39379	1972	96.3	0.222	0.222	0.264	RANDOM	50.6
