Fig. 12

Five aligned protein structures from the cytochrome P450 family. Top left part shows the 3D view and right part represents a fraction (for better illustration) of the superimposed and juxtaposed representations of the aligned chains. The superimposed view clearly shows that secondary structures marked by red rectangle are well aligned and their mutual position differs only slightly. On the other hand, the secondary structures in the blue rectangle are highly scattered in the 3D space
