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. 2. ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 3. THE MAD PHASES WERE USED AS RESTRAINTS DURING REFINEMENT. 4. NCS RESTRAINTS WERE APPLIED USING BUSTER'S LSSR RESTRAINT REPRESENTATION (-AUTONCS). 5. THE REFINEMENT WAS RESTRAINED AGAINST THE MAD PHASES. 6. THE REGION CONTAINING AN RAMACHRANDRAN OUTLIER (C221) HAS POOR DENSITY.
