ALMOST NO ELECTRON DENSITY WAS REMARK 3 OBSERVED FOR THIS RESIDUE IN THE CRYSTALLOGRAPHIC STUDY REMARK 3 INDICATING THAT THIS RESIDUE IS BADLY DISORDERED AND DOES REMARK 3 NOT PACK WELL INTO THE LATTICE. THEREFORE NO ATTEMPT WAS REMARK 3 MADE TO FIT A PCA GROUP TO THE DATA. THIS DISCREPANCY HAS REMARK 3 NO EFFECT ON THE REMAINDER OF THE STRUCTURE. REMARK 3 REMARK 3 THE SOLVENT STRUCTURE HAS BEEN DETERMINED TO THE EXTENT REMARK 3 THAT 35 PER CENT OF ALL WATERS WERE FOUND AND REFINED. THE REMARK 3 FIRST 102 WATER SITES ARE FULLY OCCUPIED AND ARE BELIEVED REMARK 3 TO BE ACCURATELY PLACED. OCCUPANCIES WERE REFINED FOR THE REMARK 3 REMAINING WATER SITES, AND THEIR POSITIONS ARE LIKELY TO BE REMARK 3 KNOWN WITH LESS ACCURACY. ALL WATER SITES INCLUDED IN THIS REMARK 3 ENTRY ARE CHEMICALLY SENSIBLE IN THAT HYDROGEN BONDS ARE REMARK 3 FORMED TO SUITABLE DONORS OR ACCEPTORS AND NO BAD PACKING REMARK 3 CONTACTS ARE FORMED. WATERS 115, 117, 118, 121 AND 123 REMARK 3 ARE PARTICULARLY SIGNIFICANT AND APPEAR TO BE INTEGRAL REMARK 3 PARTS OF THE PROTEIN STRUCTURE.
