Figure 2. Long-distance EF-hand pair-pair interactions. C superimposition of the ten lowest-energy structures of Ca^2+-loaded calbindin-D[28K], showing representative pair-pair interactions between EF1-EF2 and EF3-EF4 (a,b), and EF3-EF4 and EF5-EF6 (c,d). There is a 180° rotation about the vertical axis between a and b and between c and d.
