Modeling, docking, and docking accuracy prediction results for the complex between the human cellular retinol-binding protein II and retinol (PDB ID: 2RCT). a) and b) Experimental structure of the complex (gray), superimposed to the models obtained by using 1ICN (red) and 1OPA (blue) as templates; c) plot of predicted docking dRMSD (dRMSD-predicted) vs. calculated dRMSD (dRMSD); in black, values for the models in the subset 1CBS + 1FEN, in red and in blue, values for the models of 2RCT obtained by using 1ICN and 1OPA as templates, respectively.
