Figure 2From: A chemogenomics view on protein-ligand spacesPCA model projections. This figure shows scatter plots of first three principal components (c1, c2, and c3) of the PDB (blue) and DrugBank (red) interaction datasets. For each PCA model, the goodness of fit (R2X) for the three principal components is shown. The plots are based on (A) protein descriptors, (B) ligand descriptors, and (C) protein and ligand descriptors.Back to article page
