The solution was then spread onto approximately 60 glass plates. After vacuum drying to remove TFE, 2 microliters of sterile-filtered water was added to each plate, and the plates were then stacked into a glass tube and placed in a chamber containing a saturated solution of K2SO4 for hydration. 溶媒系: Oriented bilayers formed after equilibrating the sample in this chamber at 42C overnight. This sample container was then sealed with a microscope cover glass and epoxy to maintain sample ...溶媒系: Oriented bilayers formed after equilibrating the sample in this chamber at 42C overnight. This sample container was then sealed with a microscope cover glass and epoxy to maintain sample hydration during the experiments. |

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. |
