Two copies of the gramicidin protein are shown here (<scene name='User:Eric_Martz/Sandbox_10/Gramicidin/4'>restore initial scene</scene>) arranged as they are believed to be when they form a channel through a lipid bilayer membrane<ref name="crouzy">PMID: 7529578</ref>. The shape of the protein is shown transparent (ghostly), and a backbone trace connecting the alpha carbon atoms of each amino acid chain is opaque (solid).
