Figure 2
A packing diagram, with extracellular molecules to illustrate the two kinds of single-strand helical catemers proceeding in the b direction. Those of type-I follow an axis in the center of the cell at a = ½, while those of type-I′ follow an axis in the bc face. Methylene and methine H atoms have been omitted for clarity. Displacement ellipsoids are shown at the 20% probability level.
