Method	Details	Software
simulated annealing, torsion angle dynamics	The standard simulated annealing protocol included as part of DYANA software was used to calculate a total of 50 structures, of which 30 structures with the lowest target function values were chosen for the solution structure ensemble. The helical regions of these 30 structures were superimposed and the mean structure was obtained using MOLMOL software, then subjected to the standard variable target function minimization implemented in DYANA. The resulting minimized mean structure is deposited here. The ensemble of 30 structures is deposited in the PDB entry 2ju1.	DYANA
