HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. 3. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 4. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 5. 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. 6. SULFATE ION (SO4) AND 3-CYCLOHEXYL-1-PROPYLSULFONIC ACID (CXS) FROM THE CRYSTALLIZATION SOLUTION ARE MODELED.
