Fig 6. Three surface representations of the structure of 2,4-dienoyl-CoA reductase (PDB ID: 1PS9).

Each structure is cut with a clip plane cut through the middle of the structure, showing the core of the protein: (A) the conservation-colored structure; (B) the c-distance-colored structure, together with concentric circles in dotted line with varying radii centered at the centroid; (C) the WCN-colored structure.
