NMR Refinement
Method simulated annealing using torsion angle dynamics AND cartesian dynamics with the program CNS 1.1
Details calcium restraints were introduced only during the 2nd cooling stage using cartesian dynamics. See table 3 of the reference paper for a detailed description of the distance and dihedral restraints.

Additional NMR Experimental Information
1 The structure was determined using triple-resonance spectroscopy. The chemical shifts for TnI115-131 were obtained from a 2D_15N/13C_filtered-DIPSI experiment. Intramolecular NOEs for TnI115-131 were obtained from a 2D_15N/13C_filtered-NOESY experiment.
