Fig. 2. Delineation and fitting of cadherin molecules to the desmosome. With the C-cadherin x-ray structure as a template, 136 cadherin molecules were delineated in the region of desmosome "P" (see Table 1). (A) Densities from the map, with individual cadherin molecules in various colors and the membrane in cyan. (B) A representative group of cadherin molecules clustering at the midline and interacting predominantly at their tips. (C to E) Three recurrent molecular interactions within the molecular groups, referred to as W, S, and , respectively. The x-ray structure for C-cadherin was fitted as a rigid body with no changes within the structure itself. (G to I) The resulting juxtaposition of EC1 domains, where each molecule has a distinct ribbon color, calcium ions are brown, the space-filling representation of the Trp2 side chain is dark orange, and the HAV sequence has a light orange ribbon with stick-like side chains.
