Figure 9.

Homology model of DC3. The atomic coordinates of DC3 were assigned by Swiss-Model using calmodulin (Taylor et al., 1991) as a template. The theoretical model was rendered in Protein Explorer; the amino terminus is at the top. The four EF-hands are labeled EF1–EF4. Short antiparallel β-sheets are predicted to link adjacent loop regions, perhaps stabilizing the EF-hands (Taylor et al., 1991). An asterisk marks the predicted nonhelical region that breaks what would be a long central helix into two shorter helices. Red: alpha-helices; blue and white: loops; yellow: beta strands.
