HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. 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 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. ANOMALOUS DIFFERENCE FOURIERS AND PRESENCE OF AMMONIUM IODIDE (NH4I) IN THE CRYSTALLIZATION SOLUITION SUPPORT THE MODELING OF IOD IONS. 4. ETHYLENE GLYCOL (EDO) MOLECULES FROM THE CRYOPROTECTION SOLUTION ARE MODELED. 5. DENSITY AROUND RESIDUES 62-65 IN CHAIN A IS POOR AND DISORDERED. 6. CISPEPTIDES 120-121 IN BOTH CHAINS ARE WELL SUPPORETED BY DENSITY.
