On the Difference in Quality between Current Heuristic and Optimal Solutions to the Protein Structure Alignment Problem
Figure 11
Structural superposition of HiPIP (high-potential iron protein) from Chromatium vinosum, PDB ID: 1ckuA (black) and HiPIP isolated from the phototrophic bacterium Rhodocyclus tenuis, PDB ID: 1isuA (gray), obtained by (a) a heuristic method and (b) MaxPairs. This is another example illustrating an obvious difference in quality of two structural matches.
