REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.01 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE BACKBONE COORDINATES OBTAINED REMARK 3 FROM SOLUTION NMR WERE SUPERIMPOSED ON THE COORDINATES REMARK 3 OBTAINED FROM SOLID-STATE NMR TO FIX THE HELIX ORIENTATION AND REMARK 3 ROTATION IN THE MEMBRANE. THE PENTAMERIC ARRAY WAS THEN REMARK 3 OPTIMIZED USING MOLECULAR DYNAMICS. PORE CONTOURS WERE REMARK 3 CALCULATED WITH THE PROGRAM HOLE.
