==Overview==
[[Category: Taylor K]]
X-ray diffraction analysis at 1.5 A resolution has confirmed the helical conformation of a de novo designed 18-residue peptide. However, the crystal structure reveals the formation of continuous molecular layers of parallel-packed amphiphilic helices as a result of much more extensive helix-helix interactions than predicted. The crystal packing arrangement, by virtue of distinct antiparallel packing interactions, segregates the polar and apolar surfaces of the helices into discrete and well-defined interfacial regions. An extensive "ridges-into-grooves" interdigitation characterizes the hydrophobic interface, whereas an extensive network of salt bridges and hydrogen bonds dominates the corresponding hydrophilic interface.
