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.S-ADENOSYLMETHIONINE WAS ADDED DURING CRYSTALLIZATION. IN THIS STRUCTURE, ONLY S-ADENOSYL-L-HOMOCYSTEINE( SAH) IS MODELED IN THE CONSERVED BINDING SITE DUE TO A POSSIBLE ENZYMATICALLY RELATED DEGRADATION. AN UNKNOWN LIGAND (UNL) IS MODELED NEXT TO THE S-ADENOSYL-L- HOMOCYSTEINE IN THE SAME BINDING SITE. THE SHAPE OF THE LIGAND IS CREATINE LIKE. 5.A COBALT ION FROM THE CRYSTALLIZATION REAGENT IS MODELED IN THIS STRUCTURE. THE PRESENCE OF THE CO ATOM IS SUPPORTED BY X-RAY FLUORESCENCE MEASUREMENTS, ANOMALOUS DIFFERENCE FOURIERS AND GEOMETRY. ADDITIONAL ELECTRON DENSITY IS OBSERVED ADJACENT TO THE COBALT ION AND NEAR TO RESIDUES 203 AND 243. THIS DENSITY WAS LEFT UNMODELED. 6.AN IMIDAZOLE MOLECULE AND CHLORIDE ION FROM THE PROTEIN BUFFER, SULFATE IONS FROM THE CRYSTALLIZATION CONDITION AND ETHYLENE GLYCOL MOLECULES FROM THE CRYOPROTECTANT ARE ALSO MODELED IN THIS STRUCTURE.
