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. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 5. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT.
