The [[biological unit]] of [[5eon]] is a crystallographic structure of 6 alpha helices assembled into a fiber with a hydrophobic core<ref name="5eon">PMID: 27192036</ref>. The individual peptides are synthetic and were designed to assemble in this manner, with a hydrophotic core rich in phenylalanine. The crystal structure has a [[resolution]] of 1.7 Å (very good), and an [[Rfree]] of 0.22, which is average for this resolution, indicating that the model is reliable. | The [[biological unit]] of [[5eon]] is a crystallographic structure of 6 alpha helices assembled into a fiber with a hydrophobic core<ref name="5eon">PMID: 27192036</ref>.
