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.ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 4.WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 5.1,2-ETHANEDIOL (EDO) FROM THE CRYOPROTECTANT SOLUTION HAS BEEN MODELED IN THE SOLVENT STRUCTURE. 6.THE PROTEIN IS CLEAVED AFTER RESIDUE 147, WHICH RESULTS IN RESIDUE 148 BEING LOCATED FAR FROM RESIDUE 147.
