HYDROGENS HAVE BEEN ADDED IN 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). A ZN ATOM ON EACH OF THE TWO SUBUNITS IN THE ASYMMETRIC UNIT IS COORDINATED TO THE SIDE CHAIN OF HIS 59, HIS 101, AND ACETATE. A ZINC ATOM ON SUBUNIT B IS COORDINATED TO THE SIDE CHAINS OF GLU 136, ASP 137 AND FOUR WATER MOLECULES. ANOMALOUS DIFFERENCE FOURIERS AND X-RAY FLUORESCENCE EXPERIMENTS SUPPORT THE ASSIGNMENT OF THE ZINC IONS. (5). UNEXPLAINED ELECTRON DENSITIES OBSERVED NEAR RESIDUE 111 ON THE A SUBUNIT AND RESIDUES 141-143 ON THE B SUBUNIT WERE NOT MODELED. (6). FOUR MOLECULES OF POLYETHYLENE GLYCOL 200 (PG4) USED AS A CRYOPROTECTANT, FIVE ACETATE (ACT) AND ONE CL ION FROM THE CRYSTALLIZATION BUFFER WERE MODELED INTO THE STRUCTURE.
