IT IS LIKELY THAT THE REMARK 3 "FLAP" RESIDUES WERE ACTUALLY PRESENT IN MULTIPLE REMARK 3 CONFORMATIONS. HOWEVER, THEY WERE REFINED IN THESE REMARK 3 CONFORMATIONS WITH THEIR OCCUPANCIES SET TO 1.0. REMARK 3 CONSEQUENTLY, THEIR B-FACTORS ARE GREATER THAN THE REST REMARK 3 OF THE PROTEIN. FURTHERMORE, THE LACK OF "ENCLOSING" REMARK 3 ELECTRON DENSITY CAUSED MORE SIGNIFICANT GEOMETRIC REMARK 3 DEVIATIONS DURING REFINEMENT.
