HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. (2). A MET-INHIBITION PROTOCOL WAS USED FOR SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 TO ACCOUNT FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. (3). SODIUM IONS (NA) AND AND CHLORIDES (CL) FROM THE CRYSTALLIZATION SOLUTION WERE MODELED INTO THE STRUCTURE. (4). ETHYLENE GLYCOLS (EDO) FROM THE CRYOPROTECTION WERE MODELED INTO THE STRUCTURE.
