A MET-INHIBITION PROTOCOL WAS USED REMARK 3 FOR SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. REMARK 3 THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO REMARK 3 0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET REMARK 3 INCORPORATION. 2. ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B REMARK 3 FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U REMARK 3 FACTORS. 3. NCS RESTRAINTS WERE APPLIED USING BUSTER'S LSSR REMARK 3 RESTRAINT REPRESENTATION (-AUTONCS).4.AN UNKNOWN LIGAND (UNL) REMARK 3 WAS MODELED AT THE PUTATIVE RNA BINDING SITE.
