(2) 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 TO ACCOUNT FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. (3) EDO WAS ADDED BASED ON CRYSTALLIZATION CONDITION. (4) TLS GROUPS WERE ASSIGNED WITH THE AID OF TLSMD. (4) ATOM RECORD CONTAINS RESIDUAL B FACTORS ONLY.
