Figure 7.
Stereo view of helix A in conformation states II and V. (A) Obelin (PDB code1EL4; state II). (B) Ca^2+-loaded apo-obelin (state V). (C) Aequorin (PDB code 1EJ3, monomer B; state II). (D) Ca^2+-loaded apo-aequorin (state V). The photoprotein conformation states II and V are from Figure 1 [triangle] Figure 1.-. The residues for the Ca^2+-loaded state of apo-aequorin are numbered according to that used for the aequorin structure (PDB code 1EJ3).
