_pdbx_nmr_refine.details            
;The backbone coordinates obtained from solution NMR were superimposed on the coordinates obtained from solid-state NMR to fix the helix orientation and rotation in the membrane. The pentameric array was then optimized using molecular dynamics. Pore contours were calculated with the program HOLE.
