HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 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 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. ATOM RECORD CONTAINS 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. GLYCEROL (GOL) AND CHLORIDE (CL) MODELED ARE PRESENT IN CRYSTALLIZATION/CRYO CONDITIONS. 6. ACTIVE SITE RESIDUE CYS203 IS COVALENTLY MODIFIED. IT IS MODELED AS S-ACETONYLCYSTEINE (CSA) BASED ON DENSITY AND INTERACTION ENVIROMENT.
