Figure 1
Molecular structure of gramicidin S. The one and a half molecules of gramicidin S present in the asymmetric unit are shown in green; residues are labelled. The twofold symmetry-related half-molecule of gramicidin S is displayed in light blue. The less populated conformations of the disordered side chains of A-Orn8 and B-Leu4 are displayed in magenta. Water and trifluoroacetic acid molecules are also shown.
