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 ZN ION, ONE NI ION, TWO NA IONS, THREE ACETATE IONS AND TWO GLYCEROL MOLECULES WERE MODELED. THE PRESENCE OF THE ZN AND NI ATOMS ARE SUPPORTED BY X-RAY FLUORESCENCE MEASUREMENTS, ANOMALOUS DIFFERENCE FOURIERS ABOVE AND BELOW THE NI AND ZN ABSORPTION EDGES AND GEOMETRY. 5.RESIDUES 0 AND 185 TO 187 ARE DISORDERED AND NOT MODELED IN THE STRUCTURE.
