REMARK 3 THEIR RELATIVE WEIGHT AND THE ATOMIC POSITIONS OF THE SECOND REMARK 3 CONFORMER ARE NOT ACCURATELY DETERMINED. IN 1APH, 1BPH, AND REMARK 3 1DPH, THE SIDE CHAIN OF GLU B 21 IS DISORDERED. IT HAS BEEN REMARK 3 MODELED AS SUPERPOSITION OF TWO CONFORMATIONS BUT ATOMIC REMARK 3 POSITIONS FOR THESE CONFORMATIONS ARE PROBABLY NOT VERY REMARK 3 ACCURATE. THE MAIN AND SIDE CHAIN OF ALA B 30 (C-TERMINAL REMARK 3 RESIDUE OF CHAIN B) CAN ADOPT TWO SEPARATE CONFORMATIONS AND REMARK 3 IS DISORDERED IN EACH OF THESE CONFORMATIONS, WHICH LIMITED REMARK 3 THE ACCURACY OF DETERMINATION OF ATOMIC POSITIONS FOR THE REMARK 3 CONFORMERS OF ALA B 30. IN 1APH AND 1CPH, SINGLE ALTERNATIVE REMARK 3 CONFORMERS ARE PREDOMINANT BUT, DUE TO DISORDER, THEY ARE REMARK 3 ASSIGNED PARTIAL OCCUPANCIES. IN 1BPH AND 1DPH, BOTH REMARK 3 ALTERNATIVE CONFORMERS ARE INCLUDED IN THE ENTRY.
