REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.851 REMARK 3 AUTHORS : BRUNGER, A. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THIS ENTRY REPRESENTS THE C-TERMINAL REMARK 3 LIM DOMAIN OF THE QUAIL CYSTEINE RICH PROTEIN CRP2(LIM2) REMARK 3 CONSISTING OF 15 MINIMIZED FINAL STRUCTURES. RESIDUES MET 82 - REMARK 3 ALA 117 AND ASN 175 - GLN 194 WERE NOT OBSERVED AND THERE IS REMARK 3 NO INFORMATION REGARDING THE CONFORMATION THAT THESE RESIDUES REMARK 3 MAY ADOPT IN SOLUTION. THE ONLY STRETCH OF RESIDUES FOR WHICH REMARK 3 THERE IS STRUCTURAL INFORMATION IS GLU 118 - LYS 174 SO THE REMARK 3 SIMULATIONS WERE RESTRICTED TO THE CENTRAL PART ALA 117 - ASN REMARK 3 175, CONTAINING THE TWO ZINC KNUCKLES. IN AN INITIAL STAGE REMARK 3 ZINC WAS COVALENTLY ATTACHED TO A LINEARIZED TEMPLATE REMARK 3 STRUCTURE, THEN TETRAHEDRAL COORDINATION WAS ENFORCED BY REMARK 3 DISTANCE CONSTRAINTS. FINALLY THE ZINC IONS WERE COVALENTLY REMARK 3 ATTACHED TO THE COORDINATING RESIDUES USING STANDARD FORCE REMARK 3 FIELD PARAMETERS. 653 INTER- AND INTRA-RESIDUE NOE RESTRAINTS REMARK 3 WERE DEFINED AS STRONG, MEDIUM, WEAK AND VERY WEAK AND APPLIED REMARK 3 DURING THE FINAL REFINEMENT AS WELL AS 28 TORSION ANGLE REMARK 3 RESTRAINTS AND 15 HYDROGEN BOND RESTRAINTS. OMEGA DIHEDRAL REMARK 3 ANGLES WERE RESTRAINED TO TRANS (E). AVERAGE RMSD FROM EXP. REMARK 3 DISTANCE RESTRAINTS(ANGSTROMS) 0.01, AVERAGE RMSD FROM REMARK 3 IDEALIZED COVALENT GEOMETRY: BONDS(ANGSTROMS): 0.01; REMARK 3 ANGLES(DEG) 1.98;
