REMARK 3 PROGRAM : X-PLOR 3.1 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: CALCULATIONS OF THE N- AND C-DOMAINS REMARK 3 WERE PERFORMED SEPARATELY BECAUSE THE CENTRAL LINKER IS REMARK 3 UNSTRUCTURED AND FLEXIBLE IN SOLUTION. THE ORIENTATION OF THE REMARK 3 TWO DOMAINS WITH RESPECT TO EACH OTHER AND THE STRUCTURE OF THE REMARK 3 CENTRAL LINKER (RESIDUES 86 - 94) ARE THEREFORE UNDEFINED. THE N- REMARK 3 DOMAIN (2 - 85) AND C-DOMAIN (95 - 161) IN THIS STRUCTURE ARE REMARK 3 THE STRUCTURES IN THE ENSEMBLES CLOSEST TO THE UNMINIMIZED REMARK 3 AVERAGE STRUCTURES. IN PARTICULAR, THE N-DOMAIN HERE CORRESPONDS REMARK 3 TO MODEL 25 IN 2CTN, AND THE C-DOMAIN TO MODEL 3 IN 3CTN. THE REMARK 3 CENTRAL LINKER HERE IS THE RESULT OF ENERGY MINIMIZATION WITHOUT REMARK 3 EXPERIMENTAL RESTRAINTS, AND IS ADDED ONLY AS A TOOL OF REMARK 3 CONVENIENCE.
