Figure 6From: Structural insights into the function of the core-circadian factor TIMING OF CAB2 EXPRESSION 1 (TOC1) Models of module III in predictive complex with calcium. Structural models of module III. The colors from blue to red represent sequence length from the amino- to carboxy-terminal direction. Note that alpha-helical clusters in the carboxy terminus center these structures, and that a calcium ion can be fit into all four structures in an amino-terminal position within all structures. The red arrow points to the fit calcium, which is colored as a gray sphere.Back to article page
