REMARK   3  RESIDUAL B FACTORS. 3. ANISOU RECORDS CONTAIN SUM OF TLS AND        
REMARK   3  RESIDUAL U FACTORS. 4. WATERS WERE EXCLUDED FROM AUTOMATIC TLS      
REMARK   3  ASSIGNMENT. 5. A MET-INHIBITION PROTOCOL WAS USED FOR               
REMARK   3  SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. THE       
REMARK   3  OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO        
REMARK   3  0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET          
REMARK   3  INCORPORATION. 6. A NICKEL ION (NI+2) IS MODELED BASED ON A PEAK    
REMARK   3  IN THE ANOMALOUS DIFFERENCE FOURIER. X-RAY FLUORESCENCE EMISSION    
REMARK   3  SPECTRA SHOWED PEAKS CORRESPONDING TO THE NICKEL AND ZINC K-        
REMARK   3  EDGES. DATA SETS WERE COLLECTED ABOVE AND BELOW THE ZINC AND        
REMARK   3  NICKEL K-EDGES. COMPARING ANOMALOUS DIFFERENCE FOURIER MAPS FROM    
REMARK   3  THESE 4 DATA SETS SUGGESTS A MIXTURE WITH MORE NICKEL THAN ZINC.    
REMARK   3  7. THE MODELED PEG 200 FRAGMENTS (1PE AND PGE) AND SODIUM IONS      
REMARK   3  ARE PRESENT IN THE CRYSTALLIZATION SOLUTION AND PROTEIN BUFFER.     
REMARK   3  8. THE SCATTERING FACTORS FOR SULFUR, SELENIUM AND ZINC ATOMS       
REMARK   3  WERE ADJUSTED BY REFMAC 5.7.0032 TO ACCOUNT FOR ANOMALOUS           
REMARK   3  DISPERSION. THE SELENIUM CORRECTION WAS DERIVED FROM THE X-RAY      
REMARK   3  FLUORESCENCE MAD SCAN WITH CHOOCH. THE CORRECTIONS FOR NICKEL       
REMARK   3  AND SULFUR WERE BASED ON THE WAVELENGTH 0.97945 A (S F'= 0.18,      
REMARK   3  SE F'= -7.60, NI F'= 0.06). THE CROMER MANN VALUES LISTED IN THE
