Figure 2From: Protein-protein docking using region-based 3D Zernike descriptorsThe correlation coefficient of 3DZD and the angle between normal vectors sampled at surface points of (a), the bound and (b), unbound interface of Ras-RasGAP complex. The PDB ID is 1WQ1 and 6A21/1WER for the bound and the unbound proteins, respectively.Back to article page
