Figure 6.
Hydrogen-bond interactions between helix A and helix H, and
helix A and the C terminus in conformation states II and V. (A)
Obelin (PDB code1EL4; state II). (B) Aequorin (PDB code 1EJ3,
monomer B; state II). (C) Ca^2+-loaded apo-obelin (state V). (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 apo-aequorin are numbered
according to that used for the aequorin structure (PDB code
1EJ3).
