Refinement | Method to determine structure: MOLECULAR REPLACEMENT Starting model: 1KX5(NUCLEOSOME CORE PARTICLE) Resolution: 9→50 Å / σ(F): 0 Details: THE STRUCTURE WAS REFINED BY RIGID BODY REFINEMENT OF NUCLEOSOME POSITIONS ONLY. NO CROSSVALIDATION WAS EMPLOYED DUE TO HIGH FLUCTUATIONS OF RFREE CAUSED BY THE SMALL NUMBER OF REFLECTIONS ...Details: THE STRUCTURE WAS REFINED BY RIGID BODY REFINEMENT OF NUCLEOSOME POSITIONS ONLY. NO CROSSVALIDATION WAS EMPLOYED DUE TO HIGH FLUCTUATIONS OF RFREE CAUSED BY THE SMALL NUMBER OF REFLECTIONS IN THE TEST SET. Since the structure was solved at very low resolution, remark 500 records have been suppressed at the request of depositors.
