REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: STRUCTURES WERE CALCULATED USING A REMARK 3 SIMULATED ANNEALING PROTOCOL WITHIN XPLOR-NIH WITH TORSION ANGLE REMARK 3 MOLECULAR DYNAMICS IN THE PRESENCE OF EXPERIMENTALLY DETERMINED REMARK 3 RESTRAINTS. SOLID-STATE NMR EXPERIMENTS ON STATIC ORIENTED LIPID REMARK 3 BILAYER SAMPLES ALLOWED FOR THE MEASUREMENTS OF ANISOTROPIC REMARK 3 BACKBONE 15N CHEMICAL SHIFTS AND 15N-1H DIPOLAR COUPLINGS, WHICH REMARK 3 WERE USED AS THE EXPERIMENTAL RESTRAINTS. THE INITIAL STRUCTURE REMARK 3 WAS AN ALPHA HELIX WITH IDEAL PHI/PSI ANGLES (-61/-45). THE REMARK 3 CALCULATIONS ALSO INCLUDED THE XPLOR-NIH POTENTIAL FOR KNOWLEDGE- REMARK 3 BASED TORSION ANGLES AND THE ROUTINE TERMS ANGL, BOND AND IMPR. A REMARK 3 TOTAL OF 100 STRUCTURES WERE GENERATED AND THE 10 LOWEST ENERGY REMARK 3 STRUCTURES WERE ACCEPTED FOR ANALYSIS AND REPRESENTATION. BY REMARK 3 CONVENTION, THE BILAYER NORMAL FOR ALL OF THE ORIENTED SAMPLES IS REMARK 3 ALIGNED ALONG THE Z-AXIS OF THE CALCULATED STRUCTURES.
