Crystals of ion-free gramicidin A (P2/sub 1/2/sub 1/2/sub 1/: a = 24.61, b = 32.28, c = 32.52) have been investigated using neutron diffraction. A difference analysis of crystals soaked in ethanol/H/sub 2/O as opposed to ethanol-d/sub 6//D/sub 2/O has lead to single isomorphous replacement Fourier projections of the structure at 5-A resolution. The gramicidin dimer appears to be a 32-A-long cylinder oriented parallel to the c-axis in these crystals.
