Figure 5

Cross-eyed stereo view of the structural superposition of the three repeats in the N-terminal domain. The superposition was made with PDBeFOLD [39]. The first repeat is coloured as a spectrum from blue (N-terminus) to red (C-terminus). The second repeat is uniformly grey. The third repeat is shown in light pink for its majority that is topologically the same as the first two repeats, and dark pink for its additional β/α motif that is defined as an insertion by the structural superposition.
