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