The usefulness of validation programs during model building is suggested by the example of the triacylglycerol lipase from Pseudomonas cepacia at different stages of atomic refinement. (a) Plot from ERRAT at the initial and final stages of refinement. (b) VERIFY3D profile-window plots of the final model. The dashed line represents symmetry molecule number 1 (residues 1–320) and symmetry molecule number 2 (residues 321–640) when not in contact with each other. The solid line represents symmetry molecule 1 and 2 when in contact. This plot illustrates that the state of oligomerization can affect the 3D profile plot, giving information on the oligomerization. See Bennett et al. (1994[link]) for more details.
