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 RECORDS CONTAIN RESIDUAL B FACTORS ONLY. 4. SULFATE AND POLYETHYLENE GLYCOL FRAGMENTS MODELLED ARE PRESENT IN CYRO/CRYSTALLIZATION CONDITIONS. 5. ZINC AND IMIDAZOLE WERE TENTATIVELY MODELLED IN THE ACTIVE SITE. ZINC IS MODELED BASED ON DENSITY AN COORDINATION GEOMETRY. THE FINAL METAL ION ASSIGNMENT IS PENDING FOLLOW-UP STUDIES. IMIDAZOLE IS ASSIGNED BASED ON DENSITY, INTERACTION ENVIRONMENT AND PRESENCE IN THE PROTEIN BUFFER .
