NMR Refinement
Method	Details	Software
torsion angle dynamics	Preliminary structures were calculated using CNS1.0. These structures were then used as input into the program ARIA1.0 for noe assignment and structure refinement. These structures were calculated using 1799 unambiguous and 214 ambiguous NOEs, 14 hydrogen bond restraints, 44 dihedral angle restraints and directly refined against 33 Jhnha coupling constants.
