Method	Details	Software
simulated annealing	ALL STRUCTURE CALCULATIONS WERE CARRIED OUT USING THE AMBIGUOUS RESTRAINTS FOR ITERATIVE ASSIGNMENT OF NOES (ARIA) PROTOCOL VERSION 1.2. THE 20 BEST STRUCTURES (SORTED ACCORDING TO TOTAL ENERGY) WERE SELECTED FOR WATER REFINEMENT. WATER REFINED STRUCTURES WERE CALCULATED USING THE SLIGHTLY MODIFIED REFINEMENT SCRIPT APPLIED TO THE RECOORD DATABASE. PROCHECK AND WHATCHECK AND QUALITY INDICATORS WERE COMPARED TO THE AVERAGE VALUES FOR THE RECOORD DATABASE OF PROTEIN NMR STRUCTURES.	Analysis_(CCPN)
