Linear gramicidin D in lipidic cubic phase

Showing that small membrane peptides can be solved in meso.

Two gramicidin peptides (orange and gold) wound round each other, shown as sticks on a thin ribbon.

Structures of the peptide antibiotic gramicidin from crystals grown in the lipidic cubic phase, down to 1.08 Å resolution.
