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. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 4.ELECTRON DENSITY INDICATES THAT MYRISTIC ACID (MYR) IS FOUND IN THE SUBSTRATE-BINDING SITE OF EACH MONOMER. ITS IDENTITY IS TENTATIVELY ASSIGNED BASED ON DENSITY.
