REMARK   3  OTHER REFINEMENT REMARKS: FINAL REFINEMENT IS AFTER DETWINNING      
REMARK   3  DATA. 529 REFLECTIONS WERE REJECTED BY CNS AFTER MEROHEDRAL         
REMARK   3  DETWINNING. THE THREE CHAINS OF THE TRIMER ARE RELATED BY           
REMARK   3  CRYSTALLOGRAPHIC SYMMETRY. TO GENERATE THE TRIMER, APPLY            
REMARK   3  SYMMETRY TRANSFORMATIONS. THE FINAL MODEL CONSISTS OF ALL           
REMARK   3  RESIDUES EXCEPT FOR THE TWO N-TERMINAL RESIDUES OF C14LINKMID,      
REMARK   3  WHICH ARE DISORDERED.
