Figure 1 (IMAGE) Institute for Basic Science Caption A: Overlaid wild-type (grey) and mutant (color), experimental (orange), and predicted (blue) structures of H-NOX protein. B: Wild-type protein with residues colored by strain (a measure of structural deformation), Si; the location of the mutation (residue 71 is mutated from alanine (A) to glycine (G)) is indicated. C: Strain, Si, per residue along the protein sequence for both experimental and predicted structures; mutation location is indicated with the dotted line.
