THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 4.PHOSPHATE (PO4) FROM THE CRYSTALLIZATION BUFFER AND 1,2-ETHANEDIOL (EDO) USED AS A CRYOPROTECTANT WERE MODELED INTO THE STRUCTURE. 5. THE MODELING OF ZINC IS SUPPORTED BY X-RAY FLUORESCENCE SCANS. THE OCCUPANCY OF THE ZN ATOM WAS REDUCED TO 0.5 FOR ITS REDUCED SCATTERING INDICATED BY ELECTRON DENSITY MAPS. 6. AN UNKNOWN LIGAND (UNL) WAS MODELED AT THE PUTATIVE ACTIVE SITE.
