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. PEG MODELED IS PRESENT IN CRYO/CRYSTALLIZATION CONDITIONS. 5. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 6. ZERO-OCCUPANCY ATOMS WERE PLACED NEAR THE THREE-FOLD AXIS TO EXCLUDE SOLVENT MASK NEAR THIS REGION. 7. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT.
