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