Figure 6. Stereo view of calcium binding region in CP-ND65 (red) and the corresponding region in CP-ND65-D146N-D149N (blue). D146 and D149, which participate in calcium coordination in CP-ND65, have undergone changes in CP-ND65-D146N-D149N. The C-terminal residues, which also coordinate to calcium in CP-ND65, are disordered in CP-ND65-D146N-D149N and, hence, are not shown.
