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. THE FOLLOWING REGIONS HAVE POOR DENSITY: 125-133,332-336. 5. ETHYLENE GLYCOL MODELED ARE PRESENT IN CRYSTALLIZATION/CRYO CONDITIONS. AN ADDITIONAL LIGAND OF UNKNOWN IDENTITY (UNL) WAS MODELED.
