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 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. ATOM RECORDS CONTAIN RESIDUAL B FACTORS ONLY. 4. NADP WAS MODELED BASED ON STRUCTURAL HOMOLOGY AND DENSITY. THE OCCUPANCY IS SET TO 0.8 BASED ON DENSITY. 5. ACETATE (ACT) AND ETHYLENE GLYCOL (EDO) MODELED ARE PRESENT IN PURIFICATION BUFFER OR CRYO PROTECTANT.
