(A) Density distribution of protein binding antibodies (N pb ) in the neighbours set of protein binding (green curve) and non-protein binding antibodies (orange curve) based on surface shape similarity. (B) Density distribution of protein binding antibodies (N pb ) in the neighbours set of protein binding (green curve) and non-protein binding antibodies (orange curve) based on electrostatic surface similarity. (C) Classification performance (ROC AUC) is reported as a function of the order n of the Zernike expansion and weight of the average. (D) ROC curve of the best classifier based on shape 3DZD (blue curve), electrostatic 3DZD (red curve) and weighted average N pb (green curve).
