RESIDUES 60 - 69 WERE REFINED IN 2 CONFORMATIONS BECAUSE UPON PROTONATION OF ASP 61 AT LOW PH, ASP 61 UNDERGOES A LARGE SHIFT IN CONFORMATION AND CHANGE IN HYDROGEN BONDING. THE LOOP COMPRISING RESIDUES 61 - 69 ALSO UNDERGO CORRESPONDING CONFORMATIONAL CHANGES. HOWEVER SOME OF THESE RESIDUES ARE DISORDERED AND NOT VISIBLE IN EITHER CONFORMATION. NO ENERGY INTERACTIONS INVOLVING HOH 255, HOH 305, AND HOH 445 WERE TURNED ON DURING REFINEMENT.
