| simulated annealing | THE 18 STRUCTURES WERE SUPERIMPOSED IN ORDER TO HAVE BEST FITTING FOR THE BACKBONE ATOMS (N, CA, C) OF RESIDUES 14-134. THE EXPERIMENTAL RESTRAINTS ARE PRESENTED IN ENTRY 1INK.MR. RESIDUES 1-13 AND 135-156 ARE POORLY DEFINED BY THE EXPERIMENTAL DATA. THUS, NO MEANING SHOULD BE GIVEN TO THOSE RESIDUES' COORDINATES. | X-PLOR |

| Details | THE SOLUTION STRUCTURE OF THE TUMOR SUPPRESSOR P16INK4A HAS BEEN DETERMINED BY MULTI-DIMENSIONAL HERERONUCLEAR NMR. THE STRUCTURES WERE CALCULATED USING THE SIMULATED ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229, 129-136 USING THE PROGRAM X-PLOR 3.1 (BRUNGER). THE CALCULATION IS BASED ON 1437 EXPERIMENTAL NMR RESTRAINTS (1370 DISTANCE AND 67 TORSION ANGLE RESTRAINTS). |
