TWO OTHER MODELS OBTAINED BY REFINING AGAINST THE INDIVIDUAL DATA SETS WERE USED TO ESTIMATE ATOMIC COORDINATE ERRORS FOR THIS FINAL MODEL. THIS MODEL AND THE CORRESPONDING STRUCTURE FACTORS ARE OF UNUSUALLY HIGH QUALITY FOR THIS RESOLUTION (1.9 ANGSTROMS), WITH 97% COMPLETENESS, 9.1 FOLD REDUNDANCY (TWO DATA SETS COMBINED) AND HIGH QUALITY X-RAY SOURCE (SYNCHROTRON). THE COORDINATE ERROR IN THE FINAL MODEL, ESTIMATED FROM COMPARING THE TWO INDEPENDENTLY REFINED MODELS WAS 0.08 ANGSTROMS FOR PROTEIN ATOMS, 0.07 ANGSTROMS FOR MAIN CHAIN, 0.09 ANGSTROMS FOR SIDE CHAINS. THE OTHER TWO MODELS AND THE CORRESPONDING DATA SETS HAVE BEEN DEPOSITED SEPARATELY. | |||||||||||||||||||||||||

THE APPEARANCE OF THE ELECTRON DENSITY IS CONSISTENT WITH OE1 REPLACED BY A HYDROXYLAMINE GROUP. THE MODIFICATION IS ALSO OBSERVED IN THE STRUCTURE OF NATIVE, OXIDIZED SOD. THEREFORE, IT CANNOT BE AN ARTIFACT OF THE TREATMENT WITH DITHIONITE, USED IN REDUCING THE ENZYME. THE POSITION OF THE MODIFICATION RELATIVE TO THE ACTIVE SITE SUGGESTS A ROLE IN THE REACTION MECHANISM. SEE THE PAPER CITED ON JRNL RECORDS ABOVE FOR DETAILS. RESIDUES WITH POOR ELECTRON DENSITY: LYS A 3, LYS A 9, LYS A 23, LYS A 68, LYS A 73, LYS A 89, GLU A 107, LYS A 120, LYS A 134, LYS A 151, LYS B 23, ASN B 51, GLN B 53, LYS B 73, LYS B 89, LYS B 134, LYS B 151. A NUMBER OF CLOSE CONTACTS OCCURS BETWEEN SOLVENT MOLECULES. INSPECTION OF THE ELECTRON DENSITY CONFIRMS THAT THESE SITES ARE REAL BUT PROBABLY CORRESPOND TO PARTIALLY OCCUPIED, ALTERNATIVE SOLVENT SITES. A FEW VERY CLOSE CONTACTS OCCUR BETWEEN ATOMS WITH ZERO OCCUPANCY AND SOLVENT MOLECULES.
