simulated annealing The refined M2-TMP monomer structure was obtained by a geometrical search using a search algorithm to obtain a minimum of the global penalty function that incorporates all the orientational restraints and the CHARMM empirical function. The orientational restraints imposed on the structure during refinement are 15 15N chemical shifts and 15 15N-1H dipolar couplings from PISEMA experiments. The observed chemical shifts are compared to calculated values from the molecular coordinates and the known tensor element magnitudes and assumed tensor orientations. The refinement was carried out in vacuo with the initial coordinates of an ideal a-helix structure (3.6 residues per turn) having a range of tilt and rotational orientations with respect to the bilayer spanning the values obtained from the PISA wheels. 1

Conformer Selection Criteria The lowest energy conformer with backbone and C beta atoms is deposited, preferred rotameric states of side chains were used during the backbone structure refinement but the side chain atoms were not included in the pdb file.
