Method	Details	Software
simulated annealing	Distance restraints were derived from 15N- or 13C-resolved 3D NOESY experiments and a 2D homonuclear 1H NOESY experiment. Restraints for the backbone angles phi and psi were derived from TALOS. Stereospecific assignments of Leu, Val methyl groups were obtained using a 10% fractionally 13C-labeled sample. HN-N residual dipolar couplings were measured using a spin-state-selective 1H,15N correlation experiment in dilute liquid crystalline medium.	TopSpin
