精密化 | 解像度: 1.45→7.5 Å / σ(F): 1.6 詳細: THE FOLLOWING ATOMS HAD WEAK DENSITY AND OCCUPANCIES WERE REFINED: B 13, B 14, B 15, B 22, B 46, B 47, B 48, B 49, B 50, (TERMINUS OF ARG B 53), (TERMINUS OF ARG B 59), (TERMINUS OF ARG B 84) ...詳細: THE FOLLOWING ATOMS HAD WEAK DENSITY AND OCCUPANCIES WERE REFINED: B 13, B 14, B 15, B 22, B 46, B 47, B 48, B 49, B 50, (TERMINUS OF ARG B 53), (TERMINUS OF ARG B 59), (TERMINUS OF ARG B 84), (SIDE CHAIN OF GLU B 101), (TERMINUS OF ARG B 103), (CG, HG1, HG2, CD, OE1, OE2 OF GLU B 116), B 135, D 13, D 14, D 15, D 46, D 47, D 48, D 49, D 50, (TERMINUS OF ARG D 53), (TERMINUS OF ARG D 59), (TERMINUS OF ARG D 84), (TERMINUS OF ARG D 103), (M 9 AND M 10), (P 9 AND P 10). DISCRETELY DISORDERED ENTIRE RESIDUES WHOSE OCCUPANCIES AND STRUCTURES WERE SIMULTANEOUSLY REFINED ARE: B 60, B 61, B 62, B 63, B 64, B 65, B 66, B 67, B 68, B 69, D 61, D 62, D 63, D 64, D 65, D 66, D 67, D 68, D 69, (ACE P 0 AND CYS P 1), (CYS P 6 AND NH2 P 7). RESIDUES B 60 - B 69 AND D 60 - D 69 WERE REFINED IN 2 CONFORMATIONS BECAUSE UPON PROTONATION OF ASP 61 AT LOW PH, ASP B 61 AND ASP D 61 UNDERGO LARGE SHIFTS IN CONFORMATION AND CHANGES IN HYDROGEN BONDING. THE LOOPS COMPRISING RESIDUES B 61 - B 69 AND D 61 - D 69 ALSO UNDERGO CORRESPONDING CONFORMATIONAL CHANGES. HOWEVER SOME OF THESE RESIDUES ARE DISORDERED AND NOT VISIBLE IN EITHER CONFORMATION. ISCRETELY DISORDERED SIDE CHAINS WHOSE OCCUPANCIES AND TRUCTURES WERE SIMULTANEOUSLY REFINED WERE B 40, B 42, B 73, B 87, B 110, D 32, D 87, D 107, D 110, M 3. B 22 IS DISORDERED BETWEEN 2 CONFORMATIONS ONE OF WHICH OCCUPIES A SIMILAR REGION OF SPACE AS A TWO-FOLD RELATED B 22. PROPER REFINEMENT WITH X-PLOR IS NOT POSSIBLE BECAUSE OF THE OVERLAP OF ONE CONFORMER WITH THE SYMMETRY-RELATED COUNTERPART. THE FOLLOWING WATERS WERE USED TO ACCOUNT FOR DENSITY DUE TO THIS CONFORMER OF TYR B 22: HOH 516, HOH 519, HOH 1249. DISORDERED WATERS ARE HOH 852 WHICH IS CLOSE TO A SYMMETRY-RELATED EQUIVALENTS OF ITSELF; HOH 1284 WHICH IS CLOSE TO A SYMMETRY-RELATED EQUIVALENTS OF ITSELF AND OCCUPIES THE SPACE AVAILABLE WHEN ASN D 107 IS IN ONE OF ITS DISCRETE CONFORMATIONS; HOH 624 WHICH IS CLOSE TO HOH 1182; HOH 1026 WHICH IS CLOSE TO A SYMMETRY-RELATED EQUIVALENT OF HOH 1253; HOH 1139 THAT OCCUPIES THE REGION OF SPACE AVAILABLE WHEN ASP B 61 IS IN CONFORMATION NO. 2; HOH 1167 THAT OCCUPIES THE REGION OF SPACE AVAILABLE WHEN ASP D 61 IS IN CONFORMATION NO. 2; HOH 513 WHICH IS CLOSE TO MAIN CHAIN CARBONYL OF B 49 AND MAIN CHAIN AMIDE OF B 50; HOH 514 WHICH IS CLOSE TO B 51; HOH 1287 WHICH IS CLOSE TO O OF B 14 FOR WHICH THERE IS LITTLE DENSITY; HOH 1251 WHICH IS CLOSE TO O OF B 51; HOH 1209 WHICH IS CLOSE TO CA OF B 48. IN REFINEMENT THERE WERE NO ENERGY INTERACTIONS INVOLVING HOH 513, HOH 852, HOH 516, HOH 519, HOH 1249, HOH 1209, HOH 1251, HOH 1284, HOH 1287. DISULFIDE BOND OF PHAGE-DISCOVERED PEPTIDE IS REPLACED WITH THIOETHER. THE FOLLOWING ATOMS HAD WEAK DENSITY AND OCCUPANCIES WERE REFINED: B 13, B 14, B 15, B 22, B 46, B 47, B 48, B 49, B 50, (TERMINUS OF ARG B 53), (TERMINUS OF ARG B 59), (TERMINUS OF ARG B 84), (SIDE CHAIN OF GLU B 101), (TERMINUS OF ARG B 103), (CG, HG1, HG2, CD, OE1, OE2 OF GLU B 116), B 135, D 13, D 14, D 15, D 46, D 47, D 48, D 49, D 50, (TERMINUS OF ARG D 53), (TERMINUS OF ARG D 59), (TERMINUS OF ARG D 84), (TERMINUS OF ARG D 103), (M 9 AND M 10), (P 9 AND P 10). B 22 IS DISORDERED BETWEEN 2 CONFORMATIONS ONE OF WHICH OCCUPIES A SIMILAR REGION OF SPACE AS A TWO-FOLD RELATED B 22. PROPER REFINEMENT WITH X-PLOR IS NOT POSSIBLE BECAUSE OF THE OVERLAP OF ONE CONFORMER WITH THE SYMMETRY-RELATED COUNTERPART.
