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. IRON HAS BEEN MODELED IN THE PUTATIVE ACTIVE SITE BASED ON AN X-RAY FLUORESCENCE SCAN FOR METAL, ANOMALOUS DIFFERENCE FOURIERS, AND COORDINATION GEOMETRY. 5. PHOSPHATE IS MODELED BASED ON ELECTRON DENSITY AND PROPOSED FUNCTION.
