REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: INITIAL STRUCTURES (5000) WERE REMARK 3 CALCULATED USING THE DISTANCE GEOMETRY PROGRAMME DIANA, USING REMARK 3 A SINGLE CYCLE OF REDUNDANT DIHEDRAL ANGLE RESTRAINTS REMARK 3 [GUNTERT, P. AND WUTHRICH, K. (1991) J. BIOMOL. NMR 1, 447- REMARK 3 456]. THE 100 STRUCTURES WITH LOWEST RESIDUAL RESTRAINT REMARK 3 VIOLATIONS WERE THEN REFINED USING DYNAMICAL SIMULATED REMARK 3 ANNEALING [NILGES, M. CLORE, G.M. AND GRONENBORN, A.M. (1988) REMARK 3 FEBS LETT. 229, 317-324] IN X-PLOR. STRUCTURES WERE CALCULATED REMARK 3 USING 419 NON-REDUNDANT INTERPROTON DISTANCE RESTRAINTS, 43 REMARK 3 DIHEDRAL-ANGLE RESTRAINTS (27 PHI, 16 CHI1), AND 28 RESTRAINTS REMARK 3 DEFINING 14 HYDROGEN BONDS, GIVING AN AVERAGE OF 13.2 REMARK 3 RESTRAINTS/RESIDUE. THE ATOMIC RMS DIFFERENCES FOR RESIDUES 4 REMARK 3 - 37 OF THE FINAL FAMILY OF 20 CONFORMERS WITH RESPECT TO THE REMARK 3 MEAN COORDINATE POSITIONS ARE 0.22 /- 0.06 AND 0.62 +/- 0.08 REMARK 3 ANGSTROMS FOR THE BACKBONE AND HEAVY ATOMS, RESPECTIVELY. THE REMARK 3 CORRESPONDING PAIRWISE RMS DIFFERENCES ARE 0.31 +/- 0.07 AND REMARK 3 0.90 +/- 0.12 ANGSTROMS. RESIDUES 1 - 3 ARE DISORDERED. THE REMARK 3 DEPOSITED STRUCTURES HAVE BEEN SUPERIMPOSED FOR MINIMUM RMSD REMARK 3 OVER THE HEAVY ATOMS OF THE MEAN COORDINATE STRUCTURE. THE REMARK 3 FIRST STRUCTURE IS THAT WITH THE LOWEST OVERALL ENERGY IN THE REMARK 3 SIMPLIFIED ALL-HYDROGEN CHARMM FORCE FIELD AS IMPLEMENTED IN X REMARK 3 -PLOR.
