The peptide/lipid mixture was rehydrated and sonicated to make liposomes in a citrate-borate-phosphate (CBP) buffer (pH 8.8) with 1 mM EDTA and 10 mM amantadine at 310 K. The liposomes were pelleted by ultracentrifugation . Then the pellet was spread on glass slides and dehydrated in a 75% humidity chamber. The dehydrated slides were rehydrated with 1.5 microl liter CBP buffer per slide followed by being stacked into a glass tube and incubated at 316 K for 24 hours in 96% relative humidity. Finally, the glass tube was sealed at both ends with epoxy and two glasscaps. ; _pdbx_nmr_sample_details.solvent_system 'oriented peptide/lipid bilayer of M2_TMD and DMPC' # _pdbx_nmr_spectrometer.spectrometer_id 1 _pdbx_nmr_spectrometer.model AVANCE _pdbx_nmr_spectrometer.manufacturer Bruker _pdbx_nmr_spectrometer.field_strength 400 _pdbx_nmr_spectrometer.type ? # _pdbx_nmr_refine.entry_id 2H95 _pdbx_nmr_refine.method 'ENERGY MINIMIZATION WITH ORIENTATIONAL CONSTRAINTS' _pdbx_nmr_refine.details ;REFINEMENT WAS CARRIED OUT IN VACUO ON INITIAL MONOMER COORDINATES CONSISTING OF TWO ALPHA-HELICAL FRAGMENTS (3.6 RESIDUES PER TURN) HAVING TILT AND ROTATIONAL ORIENTATIONS WITH RESPECT TO THE BILAYER DERIVED FROM PISEMA DIPOLAR WAVE ANALYSIS.
