Figure 9. Comparison of the solution structures of the apo (blue), (Cd
2+
)1 (green) and (Ca
2+
)2 (red) states. A, Helix I
(P3--A15) and the side-chains of L6, I9, F10, Y13, A14 and A15. B, helix II (K25--F36) and the side-chains of L28, L31, L32
and F36. C, Helix III (T45--D54) and the side-chains of F50 and L53. D, Helix IV (F63--I73) and the side-chains of F63, F66,
V68, V70 and I73 together with F36. The structures have been oriented to facilitate viewing of specific structural
similarities/differences and only well-defined side-chains are shown. The Figures were prepared as for Figure 8.
