NMR Refinement
Method	Details	Software
simulated annealing	STRUCTURE DETERMINATION WAS PERFORMED BY RUNNING CYANA AND AUTOSTRUCTURE IN PARALLEL USING NOE-BASED CONSTRAINTS AND PHI AND PSI DIHEDRAL ANGLE CONSTRAINTS FROM TALOS+. CONSENSUS PEAK ASSIGNMENTS WERE SELECTED AND USED IN ITERATIVE REFINEMENT WITH CYANA. THE 20 CONFORMERS OUT OF 100 WITH THE LOWEST TARGET FUNCTION WERE FURTHER REFINED BY SIMULATED ANNEALING IN EXPLICIT WATER BATH USING THE PROGRAM CNS WITH PARAM19 FORCE FIELD.	CNS
