THE LOOPS COMPRISING RESIDUES B REMARK 3 61-B 69 AND D 61-D 69 ALSO UNDERGO CORRESPONDING REMARK 3 CONFORMATIONAL CHANGES. HOWEVER SOME OF THESE RESIDUES ARE REMARK 3 DISORDERED AND NOT VISIBLE IN EITHER CONFORMATION. TYR B 22 IS REMARK 3 DISORDERED BETWEEN 2 CONFORMATIONS ONE OF WHICH OCCUPIES A REMARK 3 SIMILAR REGION OF SPACE AS A 2-FOLD RELATED B 22. PROPER REMARK 3 REFINEMENT WITH XPLOR IS NOT POSSIBLE BECAUSE OF THE OVERLAP REMARK 3 OF ONE CONFORMER WITH THE SYMMETRY RELATED COUNTERPART. THE REMARK 3 FOLLOWING WATERS WERE USED TO ACCOUNT FOR DENSITY DUE TO THIS REMARK 3 CONFORMER OF TYR B 22: HOH 1637, HOH HOH 1777. NO HYDROGENS REMARK 3 ARE INCLUDED FOR THESE "WATERS".
