REMARK   3  RESIDUE THR 211 IS A CIS THREONINE.  IT WAS ORIGINALLY              
REMARK   3  MODELLED AS A TRANS CONFORMER.  AS OUTLINED IN REFERENCE 1          
REMARK   3  ABOVE, HOWEVER, THE MAIN CHAIN ANGLES OF THIS RESIDUE WERE          
REMARK   3  OUTSIDE THE ALLOWED REGIONS AND THE FIT TO THE ELECTRON             
REMARK   3  DENSITY WAS STILL INSUFFICIENT.  THE CIS CONFORMER GIVEN IN         
REMARK   3  THIS ENTRY FITS MUCH BETTER.  THE MODIFIED MODEL HAS BEEN           
REMARK   3  SUBJECTED TO TWO FURTHER MINICYCLES OF POSITIONAL AND B             
REMARK   3  FACTOR REFINEMENT WITHOUT GROSS CONFORMATION CHANGES AND            
REMARK   3  WITHOUT AFFECTING THE R VALUE.  TWO SITES PROBABLY OCCUPIED         
REMARK   3  BY CALCIUM IONS AND 432 SOLVENT MOLECULES WERE LOCATED.
