Figure 1.
Fig. 1. Scheme of the repetitive multiplication of the 10 residue unit during search of the initial template for the involucrin structure. α-Helical segments are represented by cylinders. The crossing angle ω was used to vary the orientation of the α-helical segments; Δz and Δφ are components of the screw translation. Circles with ‘L’ on the surface of the α-helices indicate location of leucines 5 and 8.
