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 SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 4.WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 5.IMIDAZOLE (IMD) FROM THE CRYSTALLIZATION SOLUTION HAS BEEN MODELED IN THE SOLVENT STRUCTURE.
