HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. ATOM RECORD CONTAINS RESIDUAL B FACTORS ONLY. 3. 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. 4. ONE SODIUM ION, THREE CHLORIDE IONS AND TWO GLYCEROL MOLECULES WERE MODELED. 5. RESIDUES 1 TO 4 ARE DISORDERED AND NOT MODELED IN THE STRUCTURE. 6. ELECTRON DENSITY NEAR RESIDUES 47, 119, 123 AND 150 IS UNMODELED.
