HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. ATOM RECORDS CONTAIN RESIDUAL B FACTORS ONLY. 3. 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. 4. ZINC IONS (ZN), ACETATE (ACT), AND ETHYLENE GLYCOL (EDO) FROM THE CRYSTALLIZATION/CRYOPROTECTANT SOLUTIONS HAVE BEEN MODELED INTO THE SOLVENT STRUCTURE. 5. TLS GROUPS WERE ASSIGNED WITH THE AID OF THE TLSMD SERVER.
