ZERO OCCUPANCY HYDROGENS WERE INCLUDED DURING REFINEMENT TO IMPROVE THE ANTI-BUMPING RESTRAINTS. 2. ATOM RECORDS CONTAIN SUM OF TLS AND RESIDUAL B FACTORS. 3. ANISOU RECORDS CONTAIN SUM OF TLS AND RESIDUAL U FACTORS. 4. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 5. 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. 6. MAD PHASE RESTRAINTS WERE USED DURING REFINEMENT. 7. LYSINE 195 APPEARS TO HAVE BEEN PROTECTED FROM REDUCTIVE METHYLATION AND WAS MODELED AS LYSINE. ALL OTHER LYSINES HAVE BEEN MODELED AS MLY (N-DIMETHYL-LYSINE).
