HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. ATOM RECORD CONTAINS 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. ETHYLENE GLYCOL (EDO), A CRYOPROTECTANT WAS MODELED INTO THE STRUCTURE. 5. SULFATE MOLECULES (SO4), AND POLYETHYLENE GLYCOL (PG6) FROM THE CRYSTALLIZATION SOLUTION WERE MODELED INTO THE STRUCTURE.
